@shivamp055_d73f9b3cc587ca1f You will be given an array and you need to combine all the elements of the array so that the biggest number possible is formed. For example : array = [31,1,2,4]
Possible combinations can be 31124, 31214, 42131 etc But the largest no. which can be formed is 43121 and this is what you have to return. Remember since array can be large so store your result in a string.
