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,
i wins if they pick at leasti + 1 balls of the same color.Return the number of players who win the game.
\n\nNote that multiple players can win the game.

Example 1:
\n\nInput: n = 4, pick = [[0,0],[1,0],[1,0],[2,1],[2,1],[2,0]]
\n\nOutput: 2
\n\nExplanation:
\n\nPlayer 0 and player 1 win the game, while players 2 and 3 do not win.
\nExample 2:
\n\nInput: n = 5, pick = [[1,1],[1,2],[1,3],[1,4]]
\n\nOutput: 0
\n\nExplanation:
\n\nNo player wins the game.
\nExample 3:
\n\nInput: n = 5, pick = [[1,1],[2,4],[2,4],[2,4]]
\n\nOutput: 1
\n\nExplanation:
\n\nPlayer 2 wins the game by picking 3 balls with color 4.

Constraints:
