德州扑克问题:一副牌中发五张扑克牌给你:让你判断数字的组成:
有以下几种情况:
1:四条:即四张一样数值的牌(牌均不论花色)2:三条带 一对
3:三条带两张不相同数值的牌
4:两对
5:顺子 包括 10,J,Q,K,A
6:什么都不是
7:只有一对
答案:

{

{
if(data[i]
{

data[i]=data[j];
data[j]=temp;
}
}
}
}
void test(int a[],int len)
{
int *b=new int[len];
int count=0;
bool temp=false;
for(int i=0;i
{
b[i]=a[i];
}
sort(b,5);
for(i=0;i
{
if(b[i]==b[i+1])
count++;
}
switch (count)
{
case 0:

{

}
else
printf("什么都不是");
break;
case 1:

break;
}
}

{

}
break;
case 3:

printf("四条:即四张一样数值的牌");
else
printf("三条带一对");
break;
}
}
