好吧理解有误

跪了，求大神提供错的测试数据
include
include
include
int cmp(const voida,const voidb)
{
return (int)b-(int)a;
}
int main()
{
int t,x,y,q[33],i=0,e;
scanf(“%d”,&t);
while(t–)
{
scanf(“%d”,&x);
y=0;
for(e=0;e<33;e++)
q[e]=1;
while(x/2)
{
if((x%2)!=((x/2)%2))
q[y]++;
else
y++;
x>>=1;
}
qsort(q,32,sizeof(q[0]),cmp);
printf(“case #%d:\n”,i);
printf(“%d\n”,q[0]);
}
return 0;
}
case编号没有自加，t>1的所有数据都是WA……加上以后可以ac。
