    1025 - Divisor Game.

    Easy

    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:

    • Choosing any x with 0 < x < n and n % x == 0.
    • Replacing the number n on the chalkboard with n - x.

    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.

    Example 1:

    Input: n = 2

    Output: true

    Explanation: Alice chooses 1, and Bob has no more moves.

    Example 2:

    Input: n = 3

    Output: false

    Explanation: Alice chooses 1, Bob chooses 1, and Alice has no more moves.
