Integer to binary
Given a non-negative integer n, return its binary representation as a string without any '0b' prefix and without leading zeros, except that 0 itself returns '0'. For example 13 returns '1101'. You may not use Python's bin() builtin; build the digits yourself.

State your approach and its time/space complexity out loud before you optimize. Handle the edge cases (empty input, duplicates, overflow), and say why you chose this over the brute force. Green tests are the floor, not the grade.
