Backtracking is an algorithmic technique used for solving problems incrementally by trying to build a solution piece by piece and removing those solutions that fail to satisfy the conditions of the problem. It can be viewed as a refined brute-force approach that systematically searches for a solution by exploring and abandoning paths (backtracking) when a solution cannot be obtained. Here are the key characteristics and steps involved in backtracking: 1. **Incremental Construction**: Solutions are built incrementally.
