For this Question: Given an array of N integers, your task is to calculate the largest number that can be formed by appending the numbers from the given array.
For eg:- If the numbers are { 10, 3, 31} then the largest number will be 33110First line of input contains a single integer N, next line contains N space separated integers depicting values of array.

Constraints:-
1 < = N < = 100000
1 < = Arr[i] < = 100000Print the largest number that can be formed using the array elements.Sample Input:-
3
10 3 31

Sample Output:-
33110

Sample Input:-
5
8 9 10 11 12

Sample Output:-
98121110, I have written this Solution Code: import java.io.*;
import java.util.*;



class Main {

    static void Largest(ArrayList<String> a)
    {
        Collections.sort(a, new Comparator<String>(){



        @Override
        public int compare(String X, String Y) {


        String XY=X + Y;


        String YX=Y + X;



        return XY.compareTo(YX) > 0 ? -1:1;
        }
        });

        for(String value:a)
        {
            System.out.print(value);
        }

    }
	public static void main (String[] args) throws IOException {

        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        int n=Integer.parseInt(br.readLine());
        ArrayList<String> al=new ArrayList<>();
        String[] nums=br.readLine().split("\\s");

        for(int i=0;i<n;i++)
        {
            al.add(nums[i]);
        }
        Largest(al);
	}
}, In this Programming Language: Java, Now tell me if this Code is compilable or not?
