Question
In a backtracking algorithm, what happens when a partial
solution is found to violate a constraint?Solution
The core idea of backtracking is to explore a path, and if that path leads to a dead end (violates a constraint or cannot lead to a solution), the algorithm "backtracks" by undoing the last decision and trying an alternative. This pruning of the search space is what makes backtracking efficient compared to brute-force enumeration.
