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
