题目大意：阅兵式前一天，是国王的生日，大臣们为他准备了一个 n *m(1<=n, m<=10000)的蛋糕。他准备切蛋糕，但他切蛋糕有奇奇怪怪的癖好，他每次只切一刀，切下一个正方形蛋糕。请问它最多能切出多少个正方形蛋糕？

思路：看图

 

#include <iostream>
#include <cstdio>
using namespace std;
int t;
int f(int m, int n)
{
        if(m<n) return (f(n,m));
        t += m/n;
        if(m%n==0) return 0;
        f(n,m%n);
}
int main()
{
        int m, n, T;
        scanf("%d", &T);
        while(T--)
        {
        scanf("%d%d", &m, &n);
        t=0;
        f(m, n);
        printf("%d\n", t);
        }
        return 0;
}
