Question

我认为我的算法是正确的（可能做得非常糟糕），我在ideone.com上得到了理想的输出。但是在SPOJ中，它继续说“运行时错误NZEC”。然后我添加了“sys.exit（0）”。然后NZEC错误停止了。但现在它显示“错误答案”

请建议进行一些更改以使其正确。

这是我的代码：

Answer 1

你检查

if((game_N==6 and game_D==5 ) or (game_N==5 and game_D==6)):
        curr_N=0;
        curr_D=0;
        while(game_N != 7 and game_D != 7):

这是错误。 if的条件可能后跟game_N=6,game_d=D，在你的场景中没有考虑，如果任何一个是6而另一个是5，你迭代直到任何1达到7，从而使得条件从不发生一个。
