# [3227] Vowels Game In A String
## 題目資訊
- **難度**: Medium
- **標籤**: Math, String, Brainteaser, Game Theory
- **題目連結**: https://leetcode.com/problems/vowels-game-in-a-string/
- **練習日期**: 2025-09-12
- **目標複雜度**: 時間 O(n)、空間 O(1)
## 題目描述
Alice and Bob are playing a game on a string.
You are given a string `s`, Alice and Bob will take turns playing the following game where Alice starts **first**:
On Alice's turn, she has to remove any **non-empty** substring from `s` that contains an odd number of vowels.
On Bob's turn, he has to remove any non-empty substring from `s` that contains an even number of vowels.
The first player who cannot make a move on their turn loses the game. We assume that both Alice and Bob play optimally.
Return `true` if Alice wins the game, and `false` otherwise.
The English vowels are: `a`, `e`, `i`, `o`, and `u`.
