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

 

Note: if year Y is a leap year, then the1st leap year is year Y.

 

Input

The input contains several test cases. Thefirst line of the input is a single integer T which is the number of testcases. T test cases follow.

Each test case contains two positiveintegers Y and N(1<=N<=10000).

Hint

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

题意：输入一个年份，计算从输入年份开始的第几个闰年是哪一年，并输出年份。需要考虑到闰年并不是四年一次，也有可能八年一次。闰年的判断的条件：普通年份能整除4，不能整除100，以00结尾的年份能整除400。
