[九度][何海涛] 扑克牌顺子 - chkkch - 博客园
LL今天心情特别好,因为他去买了一副扑克牌,发现里面居然有2个大王,2个小王(一副牌原本是54^_^)...他随机从中抽出了5张牌,想测测自己的手气,看看能不能抽到顺子,如果抽到的话,他决定去买体育彩票,嘿嘿!!"红心A,黑桃3,小王,大王,方片5","Oh My God!"不是顺子.....LL不高兴了,他想了想,决定大\ 王可以看成任何数字,并且A看作1,J11,Q12,K13。上面的5张牌就可以变成"1,2,3,4,5"(大小王分别看作24),"So Lucky!"LL决定去买体育彩票啦。

先排序,然后统计0的个数,然后在统计其他数字的间隔,如果0个个数大于其他数字的间隔则可以,否则不行,另外如果有相同的数字则肯定没有顺子了。
16         sort(a, a + n);
17 
18         int kingCount = 0;
19         int index = 0;
20         while(index < n && a[index] == 0)
21         {
22             kingCount++;
23             index++;
24         }
25 
26         int count = 0;
27         bool same = false;
28         for(int i = index + 1; i < n; i++)
29             if (a[i] == a[i-1])
30             {
31                 same = true;
32                 break;
33             }
34             else
35                 count += a[i] - a[i-1] - 1;
36 
37         if (same || kingCount < count)
38             cout << "Oh My God!" << endl;
39         else
40             cout << "So Lucky!" << endl;
