Ques: You have given an array of integers, using that form largest Number Possible.
Algorithm:

Source Code:(In java)

package com.array.exercise;

import java.util.Arrays;
import java.util.Comparator;

class MyCompare implements Comparator{

 public int compare(Integer i1,Integer i2){  
  String x =Integer.toString(i1);
  String y =Integer.toString(i2);
  
  String xy= x.concat(y);
  String yx= y.concat(x);
  return Integer.valueOf(xy)-Integer.valueOf(yx) > 0 ? 0:1;
 
 }
 
}
public class MakeBiggerNumber { 
 /**
  * @param args
  */
 public static void main(String[] args) {
  // TODO Auto-generated method stub
 
 
   Integer[] input = new Integer[]{54,546,548,60,77};
 
    MyCompare mc = new MyCompare();
    Arrays.sort(input,mc);
 
     for (int i = 0; i < input.length; i++) {
  System.out.print(input[i]);
 }
 }
