Percent decode URL
Percent-decode a URL-encoded string. Sequences of the form %XX (two hex digits) decode to the corresponding byte; consecutive byte escapes that form a UTF-8 multibyte sequence must decode to the correct Unicode character. Characters that are not part of an escape are passed through unchanged. Return the decoded string.

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.
