Need help in writing a backtracking code that finds a path in a given maze. The problem is that the given mazes do not have a given destination. The path exit is when you reach an edge square that is not the point of entry.Example: 1  1  1  1 0 0  0  1                       0- represents the path that we're allowed to go 1  1  0  1                        1- represents the wall 1  1  0  1                         the last zero would be the exit.   The code has to be written in c++. If you cant write the code, please at least help me with the logics. Thank you so much !!!
