Form Biggest Number

How to do this quest not able to understand this one?

@kdubey1999 For this problem you can treat the array’s elements as strings and sort them in lexicographically decreasing order. For eg. [54, 546, 548, 60] if you sort these in lexicographically decreasing order result will be [60, 548, 546, 54] , then you can print all the elements and it will form the biggest number.
