Here's the main idea:
If you can reach cell (i,j) in maze A and also in some other maze B, then you can walk infinitely. This reduces the space of your BFS to N*N (a node in your BFS consists of (i,j,mazeNumber)).
Please explain more without using BFS.
As you have to explore the state space you must use one of the exploration algorithms (BFS/DFS). Maybe I didn't understand your question properly.
I'm not really good with DFS/BFS so i was trying to solve it with another way
You'd rather learn BFS/DFS algorithms because without learning such basic algorithms you won't succeed in writing contests. At least try to learn them, they are really useful and powerful ones. Moreover, I don't see any other solution to this problem, neither simple, nor hard.
