   Write a program to find the remainder when two given numbers are divided.

   Input

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

   Output

   Find remainder when A is divided by B.

   Constraints

   • 1 ≤ T ≤ 1000
   • 1 ≤ A,B ≤ 10000
