Problem 2 Solution Topics Algorithms: Backtracking, Depth-First Search (DFS). Concepts: Combinatorial Search, State Space Trees. Optimization: Pruning (early exit). The Strategy: Recursive Backtracking The problem can be visualized as a decision tree. For every "?" encountered, we have a range of choices from 0 to day_hour. We keep track of the "remaining hours" we need to fill. Preprocessing: Calculate the current_sum of the digits already present in the string. The remaining_total we need to distribute is work_hours - current_sum. Recursive ...
