Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

The first line of the input contains an integer $$$q$$$ ($$$1 \le q \le 10^4$$$) — the number of test cases in the input. The descriptions of the test cases follow. The first line of description of each test case contains one integer $$$n$$$ ($$$1 \le n \le 50$$$) — the length of the given code. The second line of the description of each test case contains a string $$$t$$$ of length $$$n$$$ — the given code. It is guaranteed that there exists such a string of lowercase Latin letters, as a result of encoding which the string $$$t$$$ is obtained.
800
For each test case output the required string $$$s$$$ — the string that gives string $$$t$$$ as the result of encoding. It is guaranteed that such a string always exists. It can be shown that such a string is always unique.

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit.

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet.

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045).

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045).

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

Polycarp has a string $$$s$$$ consisting of lowercase Latin letters.He encodes it using the following algorithm.He goes through the letters of the string $$$s$$$ from left to right and for each letter Polycarp considers its number in the alphabet: if the letter number is single-digit number (less than $$$10$$$), then just writes it out; if the letter number is a two-digit number (greater than or equal to $$$10$$$), then it writes it out and adds the number 0 after. For example, if the string $$$s$$$ is code, then Polycarp will encode this string as follows: 'c' — is the $$$3$$$-rd letter of the alphabet. Consequently, Polycarp adds 3 to the code (the code becomes equal to 3); 'o' — is the $$$15$$$-th letter of the alphabet. Consequently, Polycarp adds 15 to the code and also 0 (the code becomes 3150); 'd' — is the $$$4$$$-th letter of the alphabet. Consequently, Polycarp adds 4 to the code (the code becomes 31504); 'e' — is the $$$5$$$-th letter of the alphabet. Therefore, Polycarp adds 5 to the code (the code becomes 315045). Thus, code of string code is 315045.You are given a string $$$t$$$ resulting from encoding the string $$$s$$$. Your task is to decode it (get the original string $$$s$$$ by $$$t$$$).

NoteThe first test case is explained above.In the second test case, the answer is aj. Indeed, the number of the letter a is equal to $$$1$$$, so 1 will be appended to the code. The number of the letter j is $$$10$$$, so 100 will be appended to the code. The resulting code is 1100.There are no zeros in the third test case, which means that the numbers of all letters are less than $$$10$$$ and are encoded as one digit. The original string is abacaba.In the fourth test case, the string $$$s$$$ is equal to ll. The letter l has the number $$$12$$$ and is encoded as 120. So ll is indeed 120120.

Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$.

Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$.

Vlad went into his appartment house entrance, now he is on the $$$1$$$-th floor. He was going to call the elevator to go up to his apartment.There are only two elevators in his house. Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.

Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.

Vlad went into his appartment house entrance, now he is on the $$$1$$$-th floor. He was going to call the elevator to go up to his apartment.There are only two elevators in his house. Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.

Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$.

Vlad went into his appartment house entrance, now he is on the $$$1$$$-th floor. He was going to call the elevator to go up to his apartment.There are only two elevators in his house. Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.

Vlad went into his appartment house entrance, now he is on the $$$1$$$-th floor. He was going to call the elevator to go up to his apartment.There are only two elevators in his house. Vlad knows for sure that: the first elevator is currently on the floor $$$a$$$ (it is currently motionless), the second elevator is located on floor $$$b$$$ and goes to floor $$$c$$$ ($$$b \ne c$$$). Please note, if $$$b=1$$$, then the elevator is already leaving the floor $$$1$$$ and Vlad does not have time to enter it. If you call the first elevator, it will immediately start to go to the floor $$$1$$$. If you call the second one, then first it will reach the floor $$$c$$$ and only then it will go to the floor $$$1$$$. It takes $$$|x - y|$$$ seconds for each elevator to move from floor $$$x$$$ to floor $$$y$$$.Vlad wants to call an elevator that will come to him faster. Help him choose such an elevator.
