2 * [3238] Find the Number of Winning Players
3 *
4 * 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.
5 * Player i wins the game if they pick strictly more than i balls of the same color. In other words,
6 * 
7 * 	Player 0 wins if they pick any ball.
8 * 	Player 1 wins if they pick at least two balls of the same color.
9 * 	...
10 * 	Player i wins if they pick at leasti + 1 balls of the same color.
11 * 
12 * Return the number of players who win the game.
13 * Note that multiple players can win the game.
14 *  
15 * <strong class="example">Example 1:
16 * <div class="example-block">
17 * Input: <span class="example-io">n = 4, pick = [[0,0],[1,0],[1,0],[2,1],[2,1],[2,0]]</span>
18 * Output: <span class="example-io">2</span>
19 * Explanation:
20 * Player 0 and player 1 win the game, while players 2 and 3 do not win.
21 * </div>
22 * <strong class="example">Example 2:
23 * <div class="example-block">
24 * Input: <span class="example-io">n = 5, pick = [[1,1],[1,2],[1,3],[1,4]]</span>

37 * Constraints:
38 * 
39 * 	2 <= n <= 10

41 * 	pick[i].length == 2
42 * 	0 <= xi <= n - 1 
43 * 	0 <= yi <= 10
