15. Tennis Set

1. 描述

In tennis, the winner of a set is based on how many games each player wins. The first player to win 6 games is declared the winner unless their opponent had already won 5 games, in which case the set continues until one of the players has won 7 games.
在网球比赛中，每局的胜负取决于每位选手赢了多少局。第一个赢得 6 局的玩家被宣布为获胜者，除非他们的对手已经赢得了 5 局，在这种情况下，该局将继续进行，直到其中一名玩家赢得 7 局。

Given two integers score1 and score2, your task is to determine if it is possible for a tennis set to be finished with a final score of score1 : score2.
给定两个整数 score1 和 score2 ，您的任务是确定网球组是否有可能以 score1 : score2 的最终比分结束。

2. 例子

• For score1 = 3 and score2 = 6, the output should be
  对于 score1 = 3 和 score2 = 6 ，输出应该是
  solution(score1, score2) = true.  solution(score1, score2) = true 。

  Since player 1 hadn’t reached 5 wins, the set ends once player 2 has won 6 games.
  由于玩家 1 尚未达到 5 胜利，一旦玩家 2 赢得了 6 场比赛，该盘就结束了。

• For score1 = 8 and score2 = 5, the output should be
  对于 score1 = 8 和 score2 = 5 ，输出应该是
  solution(score1, score2) = false.  solution(score1, score2) = false 。

  Since both players won at least 5 games, the set would’ve ended once one of them won the 7th one.
  由于两名球员都至少赢得了 5 场比赛，因此一旦其中一名球员赢得了 7th 场比赛，比赛就结束了。

• For score1 = 6 and score2 = 5, the output should be
  对于 score1 = 6 和 score2 = 5 ，输出应该是
  solution(score1, score2) = false.  solution(score1, score2) = false 。

  This set will continue until one of these players wins their 7th game, so this can’t be the final score.
  这盘比赛将持续到其中一名球员赢得他们的 7th 比赛，所以这不是最终比分。

3. 思路

主要还是逻辑判断，根据题目的要求来分析：

1. 谁先到达 6，且对手小于 5，完成比赛
2. 否则，如果有一个到了 5，就得要求对手到 7
3. 其它的情况都是 False

4. 代码

if max(score1, score2) == 6 and min(score1, score2)<5:
	return True
elif 5<=min(score1,score2)<=6 and max(score1,score2)==7:
	return True
else:
	return False

再来一行代码的：

return True if max(score1,score2)==6 and min(score1,score2)<5 else True if 5<=min(score1,score2)<= 6 and max(score1,score2)==7 else False
