1728. Cat and Mouse II

A game is played by a cat and a mouse named Cat and Mouse.

The environment is represented by a grid of size rows x cols, where each element is a wall, floor, player (Cat, Mouse), or food.

• Players are represented by the characters 'C'(Cat),'M'(Mouse).
• Floors are represented by the character '.' and can be walked on.
• Walls are represented by the character '#' and cannot be walked on.
• Food is represented by the character 'F' and can be walked on.
• There is only one of each character 'C', 'M', and 'F' in grid.

Mouse and Cat play according to the following rules:

• Mouse moves first, then they take turns to move.
• During each turn, Cat and Mouse can jump in one of the four directions (left, right, up, down). They cannot jump over the wall nor outside of the grid.
• catJump, mouseJump are the maximum lengths Cat and Mouse can jump at a time, respectively. Cat and Mouse can jump less than the maximum length.
• Staying in the same position is allowed.
• Mouse can jump over Cat.

The game can end in 4 ways:

• If Cat occupies the same position as Mouse, Cat wins.
• If Cat reaches the food first, Cat wins.
• If Mouse reaches the food first, Mouse wins.
• If Mouse cannot get to the food within 1000 turns, Cat wins.

Given a rows x cols matrix grid and two integers catJump and mouseJump, return true if Mouse can win the game if both Cat and Mouse play optimally, otherwise return false.

 

Example 1:

Input: grid = ["####F","#C...","M...."], catJump = 1, mouseJump = 2
Output: true
Explanation: Cat cannot catch Mouse on its turn nor can it get the food before Mouse.

Example 2:

Input: grid = ["M.C...F"], catJump = 1, mouseJump = 4
Output: true

Example 3:

Input: grid = ["M.C...F"], catJump = 1, mouseJump = 3
Output: false

Example 4:

Input: grid = ["C...#","...#F","....#","M...."], catJump = 2, mouseJump = 5
Output: false

Example 5:

Input: grid = [".M...","..#..","#..#.","C#.#.","...#F"], catJump = 3, mouseJump = 1
Output: true

 

Constraints:

• rows == grid.length
• cols = grid[i].length
• 1 <= rows, cols <= 8
• grid[i][j] consist only of characters 'C', 'M', 'F', '.', and '#'.
• There is only one of each character 'C', 'M', and 'F' in grid.
• 1 <= catJump, mouseJump <= 8
