REMAINDER

• Problem Description

  
  Write a program to find the remainder when two given numbers are divided. he first line contains an integer T, total number of test cases. Then follow T lines, each line contains two Integers A and B. Find remainder when A is divided by B

• CODING ARENA::

• #include <stdio.h>

  int main()

  {

    int a,b,c,i,n;

    scanf("%d",&n);

    for (i=0;i<n;i++)

    {

      scanf("%d\t%d\n",&a,&b);

      c=a%b;

      printf("%d\n",c);

    }

  
  

  return 0;

  }
