A person wants to play a game with the goal of defeating opponents at each level. Initially, there are 'n' opponents at the first level, with initial_players[i] corresponding to each opponent's strength. Then, a list named next_players is provided, representing the strength of players added with each new level. The goal is to defeat the player ranked at 'rank' in terms of strength at each level (as new players are added, the positions of existing players do not change). Each time an opponent is defeated, the player's health decreases by that opponent's strength. To ensure survival till the end, the task is to find the minimum initial health required so that the player's health is greater than or equal to zero at the end. For this question, I maintained a min heap of size 'rank'.
