Stone removal game

CodingAlgorithms & data structuresMid–Senior~25 min

A single pile has `n` stones. On each turn a player must remove a number of stones equal to one of the allowed values in `moves`. Players alternate; the player who cannot move loses (normal play). With optimal play and the first player to move, return True if the first player wins.

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.
