 ## Description
 
+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`.
+
 **Example 1:**
 
 ```
-Input: a = "11", b = "1"
-Output: "100"
-```
+Input: s = "leetcoder"
+
+Output: true
+
+Explanation:
+Alice can win the game as follows:
 
-## 题意
-> ...
+Alice plays first, she can delete the underlined substring in s = "leetcoder" which contains 3 vowels. The resulting string is s = "der".
+Bob plays second, he can delete the underlined substring in s = "der" which contains 0 vowels. The resulting string is s = "er".
+Alice plays third, she can delete the whole string s = "er" which contains 1 vowel.
+Bob plays fourth, since the string is empty, there is no valid play for Bob. So Alice wins the game.

-Vowels Game in a String
-```go
 ```
+Input: s = "bbcd"
+
+Output: false
 
+Explanation:
+There is no valid play for Alice in her first turn, so Alice loses the game.
