Largest Number (LC 179)

You are given a list of non-negative integers. Your task is to arrange them such that, when their decimal string representations are concatenated, the resulting number is as large as possible.

For any two strings x and y, prefer placing x before y if the concatenation $$x + y$$ is lexicographically larger…
