1025. Divisor Game (C++)
Problem Setting¶
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.
