heres the link for the question "Divan and a new Project" [](https://codeforces.net/contest/1614/problem/B)

Why wont this solution work? It prints the correct minimum time taken and also prints the coordinates properly. But when i submit it shows error on the first testcase and says — "wrong answer answer is wrong: pans = 14 is not equal real_pans = 18 (test case 1)" i dont get this. the answer to the first example is 14 why is it saying its 18?

import java.util.*;
public class divan {

        for(int i=0;i<t;i++){
            int n=sc.nextInt();
            int []arr=new int[n];

            for(int j=0;j<n;j++)arr[j]=sc.nextInt();

            Arrays.sort(arr);
