Largest Number

Given a list of non-negative integers, arrange them such that they form the largest possible number. In other words, you are to create a single number by concatenating the numbers after reordering them, so that the resulting number is as large as possible.

For example, given the numbers (10) and (2), the largest number is (210). Likewise, for (3, 30, 34, 5, 9), the answer is (9534330).
