Help me in solving SMOL problem

My issue

I have solved the problem and it is also running but as I submit the problem it is showing runtime error.

My code

/* package codechef; // don't place package name! */

import java.util.*;
import java.lang.*;

/* Name of the class has to be "Main" only if the class is public. */
class Codechef
	public static void main (String[] args) throws java.lang.Exception
	    Scanner sc = new Scanner(;
	    int t = sc.nextInt();
		    int x=sc.nextInt();
		    int y=sc.nextInt();
		    int r= x%y;

Learning course: Level up from 1* to 2*
Problem Link: CodeChef: Practical coding for everyone

make separate case for y==0 to avoid run time error.
