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:
x with 0 < x < N and N % x ==
0.
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: 2 Output: true Explanation: Alice chooses 1, and Bob has no more moves.
Example 2:
Input: 3 Output: false Explanation: Alice chooses 1, Bob chooses 1, and Alice has no more moves.
Note:
1 <= N <= 1000
