If you are new to dynamic programming, then you should definetly try out this problem.

Problem

Problem description Alice and Bob take turns playing a game, with Alice starting first.

Try it

Initially, there is a number n on the chalkboard. On each player's turn, that player makes a move consisting of:

Choosing any XX X with 0<X<n0 < X < n 0<X<n and n%X==0n \% X == 0 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. Exmaple 2 Input: n = 3 Output: false Explanation: Alice chooses 1, Bob chooses 1, and Alice has no more moves. Constraints 1<=n<=10001 <= n <= 1000 1<=n<=1000
