WebIntroduction : Backtracking is a type of technique that is based on a particular algorithm to solve a basic problem. It basically uses the recursive call function to get a particular solution by creating or building a solution stepwise with increasing values and time. This algorithm is applied to the particular specific types of problems : WebAs given above this algorithm involves deep recursion which may cause stack overflow issues on some computer architectures. The algorithm can be rearranged into a loop by storing backtracking information in the maze itself. This also provides a quick way to display a solution, by starting at any given point and backtracking to the beginning.
