My issue

My code

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

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

/* 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(System.in);
		int t = sc.nextInt();
		
		while (t-- > 0) {
            int n = sc.nextInt(); // maximum tastiness
            int s = sc.nextInt(); // sum of tastiness of two dishes
            
            int maxDifference = Math.abs(s - 2 * n);
            System.out.println(maxDifference);
        }
	}
}

pseudo code for maxDifference = Math.abs(2*min(n,s)- s), since max value of a taste is minimun of sum and n, according to given constraints. Hope this is helpful
