LeetCode Problem

Divisor Game

Alice and Bob take turns playing a game, with Alice starting first. Initially, there is a number n on the chalkboard. On each player's turn, that player makes a move consisting of: Also, if a player cannot make a move, they lose the game. Return true if and only if Alice wins the game, assuming both players play optimally.
