1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;

Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.

In the second example, Tokitsukaze already has a koutsu.
In the third example, Tokitsukaze can get a shuntsu by drawing one suited tile β 1p or 4p. The resulting tiles will be [3p, 9m, 2p, 1p] or [3p, 9m, 2p, 4p]. | 2 | 8 | """

1191_B. Tokitsukaze and Mahjong | Tokitsukaze is playing a game derivated from Japanese mahjong. In this game, she has three tiles in her hand. Each tile she owns is a suited tile, which means it has a suit (manzu, pinzu or souzu) and a number (a digit ranged from 1 to 9). In this problem, we use one digit and one lowercase letter, which is the first character of the suit, to represent a suited tile. All possible suited tiles are represented as 1m, 2m, β¦, 9m, 1p, 2p, β¦, 9p, 1s, 2s, β¦, 9s.
In order to win the game, she must have at least one mentsu (described below) in her hand, so sometimes she should draw extra suited tiles. After drawing a tile, the number of her tiles increases by one. She can draw any tiles she wants, including those already in her hand.
Do you know the minimum number of extra suited tiles she needs to draw so that she can win?
Here are some useful definitions in this game:
* A mentsu, also known as meld, is formed by a koutsu or a shuntsu;
* A koutsu, also known as triplet, is made of three identical tiles, such as [1m, 1m, 1m], however, [1m, 1p, 1s] or [1m, 4m, 7m] is NOT a koutsu;
* A shuntsu, also known as sequence, is made of three sequential numbered tiles in the same suit, such as [1m, 2m, 3m] and [5s, 7s, 6s], however, [9m, 1m, 2m] or [1m, 2p, 3s] is NOT a shuntsu.
Some examples:
* [2m, 3p, 2s, 4m, 1s, 2s, 4s] β it contains no koutsu or shuntsu, so it includes no mentsu;
* [4s, 3m, 3p, 4s, 5p, 4s, 5p] β it contains a koutsu, [4s, 4s, 4s], but no shuntsu, so it includes a mentsu;
* [5p, 5s, 9m, 4p, 1s, 7p, 7m, 6p] β it contains no koutsu but a shuntsu, [5p, 4p, 6p] or [5p, 7p, 6p], so it includes a mentsu.
Note that the order of tiles is unnecessary and you can assume the number of each type of suited tiles she can draw is infinite.
Input
The only line contains three strings β the tiles in Tokitsukaze's hand. For each string, the first character is a digit ranged from 1 to 9 and the second character is m, p or s.
Output
Print a single integer β the minimum number of extra suited tiles she needs to draw.
