【链接】 我是链接,点我呀:)
【题意】

在这里输入题意

【题解】

发牌的那个牌堆用一个deque,7个牌堆用vector来模拟。 然后按照题意模拟就好。 不难。

【代码】

/*
1.Shoud it use long long ?
2.Have you ever test several sample(at least therr) yourself?
3.Can you promise that the solution is right? At least,the main ideal
4.use the puts("") or putchar() or printf and such things?
5.init the used array or any value?
6.use error MAX_VALUE?
7.use scanf instead of cin/cout?
8.whatch out the detail input require
