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
Hint
We call year Y a leap year only if (Y%4==0 && Y%100!=0) or Y%400==0.

问题描述
Ignatius出生在闰年，所以他想知道什么时候可以举办他的生日派对。你能告诉他吗？
给定表示起始年份的正整数Y和正整数N，您的任务是告诉从Y年开始的第N个闰年。
注意：如果Y年是闰年，那么第一个闰年是Y年。
输入
输入包含几个测试用例。输入的第一行是单个整数T，它是测试用例的数量。 T测试案例如下。
每个测试用例包含两个正整数Y和N（1 <= N <= 10000）。
产量
对于每个测试用例，您应该从Y年输出第N个闰年。
样本输入
3
2005年25
1855年12月
2004年10000
样本输出
2108
1904
43236
暗示
只有当（Y％4 == 0 && Y％100！= 0）或Y％400 == 0时，我们才将Y年称为闰年。
