Question #53876

Given a square maze (A) of dimension N, every entry (Aij) in the maze is either an open cell 'O' or a wall 'X'. A rat can travel to its adjacent locations (left, right, top and bottom), but to reach a cell, it must be open. Given the locations of R rats, can you find out whether all the rats can reach others or not.

Input Format:

Input will consist of three parts, viz.

1. Size of the maze (N)

2. The maze itself (A = N * N)

3. Number of rats (R)

4. Location of R rats (Xi, Yi)
