LeetCode ProblemFind the Number of Winning Players
You are given an integer n representing the number of players in a game and a 2D array pick where pick[i] = [xi, yi] represents that the player xi picked a ball of color yi. Player i wins the game if they pick strictly more than i balls of the same color. In other words, Return the number of players who win the game. Note that multiple players can win the game.
