Problem Description

It is the king's birthday before the military parade . The ministers prepared a rectangle cake of size n×m(1≤n,m≤10000) . The king plans to cut the cake himself. But he has a strange habit of cutting cakes. Each time, he will cut the rectangle cake into two pieces, one of which should be a square cake.. Since he loves squares , he will cut the biggest square cake. He will continue to do that until all the pieces are square. Now can you tell him how many pieces he can get when he finishes.

 

Input

The first line contains a number T(T≤1000), the number of the testcases.

For each testcase, the first line and the only line contains two positive numbers n,m(1≤n,m≤10000).

 

Output

For each testcase, print a single number as the answer.

 

Sample Input

22 32 5

 

Sample Output

34hint:For the first testcase you can divide the into one cake of $2\times2$ , 2 cakes of $1\times 1$

题目大意：给一个n*m的蛋糕，每次只能切出一个正方形，输出最多能切多少个正方形。

解题思路：以最小边为基础，每次都切最小边那么大的正方形。。。以此类推

详见代码。

#include <iostream>#include <cstdio>using namespace std;int main(){    int t;    scanf("%d",&t);    while (t--)    {        int n,m;        scanf("%d%d",&n,&m);        int ans=0;        //int s=n*m;        while(n!=0&&m!=0)        {            //s-=n*n;            if (m>=n)                m-=n;            else                n-=m;            ans++;        }        //while (n>=m)        //{        //    n=-m;        //    ans++;        //}        cout<<ans<<endl;    }    return 0;}
