To solve the problem of finding the maximum number of trials required to open a lock when there are `n` locks and `n` matching keys, we can follow these steps: ### Step-by-Step Solution: 1. **Understanding the Problem**: We have `n` locks and `n` keys, where each key corresponds to exactly one lock. The goal is to determine the maximum number of trials needed to find the correct key for a specific lock. **Hint**: Think about the worst-case scenario where you have to try multiple keys before finding the correct one. ...
