How can I manipulate an array to make the largest number?

Question

Say you have an array of positive integers, manipulate them so that the concatenation of the integers of the resultant array is the largest number possible. Ex: {9,1,95,17,5}, r

Answer 1

I guess it has already been solved. Here are few lines of code in Python using the logic already discussed in few of the answers:

>>li = [9,1,95,17,5]
>>li.sort(cmp=lambda a,b: cmp(int(str(a)+str(b)), int(str(b) + str(a))), reverse=True)

>>output = ""
>>for i in li:
output += str(i)

>>print  output
