From Stack and Queue data structures which data structure you will suggest using for entry to exit path finding module? Select a data structure and give comments in favour to justify your selection. Also mention why you are not selecting the other data structure?
I Would suggest Stack data structure over Queue. This is because in solving a maze problem, we need to explore all possible paths. Along with that, we also need to track the paths visited.
If we were to use Queue, then after finding an unsuccessful path, we’ll have to start again from the entry point as queue only supports deletion from the front (FIFO property). This would not be useful in our case, as we need to trace back the unsuccessful path until we find another way.
Using Stack, what we can do is, while moving into the maze, we can push the index of the last visited cell and when reached the end of the maze(not exit-point), just keep popping elements from the stack until the cell at stack Top has another way to move.
Using this approach (particularly stack), you can find the correct path in the shortest possible time.
