ABSTRACT
Backtracking is the approach to a dilemma, based on prior moves. In a labyrinth problem, for example, the strategy relies on all the steps you take. If one such move is false, then the answer is not going to be found. We pick a direction in a labyrinth dilemma and keep going forward. But when we know that the course is false, then we just return and change it. This is simply backtracking.
