You are given an integer array matches where matches[i] = [winneri, loseri] indicates that the player winneri defeated player loseri in a match.

\n\n

Return a list answer of size 2 where:

\n\n\n\n

The values in the two lists should be returned in increasing order.

Example 1:

\n\n
\nInput: matches = [[1,3],[2,3],[3,6],[5,6],[5,7],[4,5],[4,8],[4,9],[10,4],[10,9]]\nOutput: [[1,2,10],[4,5,7,8]]\nExplanation:\nPlayers 1, 2, and 10 have not lost any matches.\nPlayers 4, 5, 7, and 8 each have lost one match.\nPlayers 3, 6, and 9 each have lost two matches.\nThus, answer[0] = [1,2,10] and answer[1] = [4,5,7,8].\n
\n\n

Example 2:

\n\n
\nInput: matches = [[2,3],[1,3],[5,4],[6,4]]\nOutput: [[1,2,5,6],[]]\nExplanation:\nPlayers 1, 2, 5, and 6 have not lost any matches.\nPlayers 3 and 4 each have lost two matches.\nThus, answer[0] = [1,2,5,6] and answer[1] = [].\n

示例 1：

\n\n
\n输入：matches = [[1,3],[2,3],[3,6],[5,6],[5,7],[4,5],[4,8],[4,9],[10,4],[10,9]]\n输出：[[1,2,10],[4,5,7,8]]\n解释：\n玩家 1、2 和 10 都没有输掉任何比赛。\n玩家 4、5、7 和 8 每个都输掉一场比赛。\n玩家 3、6 和 9 每个都输掉两场比赛。\n因此，answer[0] = [1,2,10] 和 answer[1] = [4,5,7,8] 。\n
\n\n

示例 2：

\n\n
\n输入：matches = [[2,3],[1,3],[5,4],[6,4]]\n输出：[[1,2,5,6],[]]\n解释：\n玩家 1、2、5 和 6 都没有输掉任何比赛。\n玩家 3 和 4 每个都输掉两场比赛。\n因此，answer[0] = [1,2,5,6] 和 answer[1] = [] 。\n
