Problem Description
Ignatius was born in a leap year, so he want to know when he could hold his birthday party. Can you tell him?

Given a positive integers Y which indicate the start year, and a positive integer N, your task is to tell the Nth leap year from year Y.

Note: if year Y is a leap year, then the 1st leap year is year Y.

 

Input
The input contains several test cases. The first line of the input is a single integer T which is the number of test cases. T test cases follow.
Each test case contains two positive integers Y and N(1<=N<=10000).

 

Output
For each test case, you should output the Nth leap year from year Y.

 

Sample Input
3
2005 25
1855 12
2004 10000
 

Sample Output
2108
1904
43236







题目在上面，我想问问 为什么是2004 年以后的第10000个是43236啊？


我写的程序是
#include <stdio.h>
void main ()
{
    int N,n,Y,i;
    scanf("%d",&N);
    for(i=0;i<N;i++)
    {
        scanf("%d%d",&Y,&n);
        flag:;
        if((Y%4==0&&Y%100!=0)||Y%400==0)printf("%d\n",Y+4*n);
        else
        {
            Y++;
            goto flag;
        }
    }
}
