My code

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

class Codechef
{
    public static void main(String[] args) throws java.lang.Exception
    {
        // your code goes here
        Scanner in = new Scanner(System.in);
        int t = in.nextInt();
        while (t--> 0) {
            int n = in.nextInt();
            int x = in.nextInt();
            int hp[] = new int[n];
            int max1[] = new int[n];
            for (int i = 0; i < n; i++) {
                hp[i] = in.nextInt();
            }
            Arrays.sort(hp);
            for (int i = 0; i < n; i++) {
                max1[i] = hp[i] + x * (n - 1 - i);
            }
            int o = Arrays.stream(max1).max().getAsInt();
            System.out.println(o);
            // int num=hp[0];
            // if((hp[n-1])>=(x*(n-1)+ num)){
            //     System.out.println(hp[n-1]);
            // }else
            // System.out.println(x*(n-1)+ num);
        }
        in.close();
    }
}
