Leetcode 2383. Minimum Hours of Training to Win a Competition

Determine the minimum number of +1 training hours to energy and experience so you can beat a sequence of opponents who require strictly greater energy (which is consumed) and experience (which increases) for each fight. The core idea is a greedy simulation: ensure energy is > total energy sum (train to sum(energy)+1) and iteratively increase experience whenever your current experience is ≤ an opponent's experience.
