You are a maze-solving agent playing a pixelated maze videogame. |
|
Mazes are presented on grid maps, where each tile can be empty land, or contain a player, hole, or goal. |
|
Each of the above tile types are represented as square pixel art images. |
|
|
|
In this task, you will analyze a grid-based map and determine if a provided action plan is safe. A safe action plan avoids stepping into holes in the map. |
|
The following figure illustrates the appearances of the player, holes, lands, and the goal within the maze. |

## Moving Rules |
|
- The action plan involves a series of moves: 'L' (left), 'R' (right), 'U' (up), or 'D' (down). |
|
- Each move transfers the player to the adjacent square in that direction, provided it is a safe square. The player cannot move more than one square at a time. |
|
- Moving off the edge of the map has no effect. The player will remain at the same square. |
|
- DO NOT MOVE INTO A HOLE! Falling into a hole results in defeat. |
|
- Locating at the grid containing the goal results in victory. |
|
We provide an example to further illustrate the rules. |
|

In this provided example: |
|
- The player is at Row 1, Column 1; |
|
- The goal is at Row 4, Column 4; |
|
- There are two holes: one at Row 1, Column 2, and another at Row 4, Column 1. |
|
- The player can move DOWN. This is because moving down brings them to Row 2, Column 1, and this cell is safe (without holes). |
|
- Moving UP has no effects. This is because the player is already in the topmost row. |
|
- Similarly, moving LEFT has no effects because the player is already in the left-most column. |
|
- Moving RIGHT places the player at Row 1, Column 2. Since there is a hole at this grid, this move results in a loss. |

## Procedure and Output |
|
Your output should include the following parts: |
|
1. First, interpret map. List where the player is at now, where is the goal, and where are the holes. |
|
2. Then, reasoning by following the given action plan. At each step, you should check: |
|
(a) Where the current move leads the player to (the row and column); |
|
(b) What is in that grid. Is it a hole? Is it the goal? Is it an empty space? |
|
(c) Determine if that is a safe action. |
|
3. Output if the action sequence is safe using "<Output> Yes" or "<Output> No". A safe action sequence should not include any unsafe actions. |
|

|
Now please determine if the action sequence is safe for this given maze: |
