Problem Statement

Given a set of positive integers, write a function to order the integers in such a way that the concatenation of the numbers forms the largest possible integer and return this integer. Use the following two sets of integers as tests   and   show your program output here.

Let's start with the solution:

maxlen=: [: >./ #&>
maxnum=: (0 ". ;)@(\: maxlen $&> ])@(8!:0)


   maxnum&> 1 34 3 98 9 76 45 4 ; 54 546 548 60
998764543431 6054854654
