Ternary expression evaluator
Given a string representing arbitrarily nested ternary expressions, evaluate it and return the result as a string. The expression uses single-digit numbers `0-9` and the letters `T` (true) and `F` (false) as conditions, with the form `condition?if_true:if_false`. Grouping is right-to-left associative and the input is guaranteed valid. Return the final single-character result.

["T?2:3"]out"2"What a strong answer looks like
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.
