A Mathematical Curiosity

#include <iostream>
using namespace std;

int main()
{
int N,n,m,num,NUM,block;
cin >> N;
block=0;
for(int x=1; x<=N; x++)
{
block +=1;
NUM=0;
while(cin >> n >> m)
{
num=0;
NUM +=1;
if(n==0 && m==0) break;//00居然是每个方块的结束标志，一开始以为是整个输入的结束，纠结好久怎么根据空行断数据……
for(int a=1; a<n-1; a++)
{
for(int b=a+1; b<n; b++)
{
if((a*a+b*b+m)%(a*b)==0)
num +=1;
}
}
cout << "Case " << NUM << ": " << num << endl;
}
if(block != N)//在输出方块之间断行
cout << endl;
}
return 0;
}
