Write a program to find the remainder when an integer A is divided by an integer B.

Input

The first line contains an integer T, the total number of test cases. Then T lines follow, each line contains two Integers A and B.

Output

For each test case, find the remainder when A is divided by B, and display it in a new line.

Constraints

  • 1 ≤ T ≤ 1000
  • 1 ≤ A,B ≤ 10000

Sample 1:

Input 
3 
1 2
100 200
40 15
Output
 
1
100
10

Solution

t = int(input())

for _ in range(t):
    a, b = map(int, input().split())
    print(a % b)
