回复 10楼神龙赖了

嗯，谢谢！
只是就算是把循环改了，依旧无法解决我之前提出的问题，搞个printf后，出现的那个"syntax error at end of input",
不知道后面有没有大神能给出这个问题解答，分数奉上！

总提交:1 测试通过:0
描述

算二十四点是个很好玩的扑克牌游戏，给4张的A－K的扑克牌，分别代表1－13，随意组合这四张牌，只使用 "+ - * /" 的四则运算，不使用其他运符和括号。请判断给定的四张牌是否可以算出二十四点。

输入

第一行为整数n，表示下面有n组数据。每组数据一行，分别为四个用空格隔开的整数，表示四张扑克牌。

输出

对于每组数据，输出一行，如果可以算出二十四点，输出"Yes."，否则输出"No."。

样例输入

2
2 11 1 1
1 1 1 1

样例输出

Yes.
No.
