Understanding the Minimum Time to Break Locks I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
Bob is stuck in a dungeon and must break n locks, each requiring some amount of energy to break. The required energy for each lock is stored in an array called strength where strength[i] indicates the energy needed to break the ith lock. To break a lock, Bob uses a sword with the following characteristics: The initial energy of the sword is 0. The initial factor x by which the energy of the sword increases is 1. Every minute, the energy of the sword increases by the current factor x. To break the ith lock, the energy of the sword must reach at least strength[i]. After breaking a lock, the energy of the sword resets to 0, and the factor x increases by a given value k. Your task is to determine the minimum time in minutes required for Bob to break all n locks and escape the dungeon. Return the minimum time required for Bob to break all n locks.
