CF1476A.divisible Sum
divisible Sum
You are given two integers and .
You should create an array of positive integers such that the sum is divisible by and maximum element in is minimum possible.
What is the minimum possible maximum element in ?
Input
The first line contains a single integer () — the number of test cases.
The first and only line of each test case contains two integers and (; ).
Output
For each test case, print one integer — the minimum possible maximum element in array such that the sum is divisible by .
Note
In the first test case , so the array consists of one element and if we make it will be divisible by and the minimum possible.
In the second test case, we can create array . The sum is divisible by and the maximum is equal to .
In the third test case, we can create array . The sum is divisible by and the maximum is equal to .
