1704. Determine if String Halves Are Alike Easy

1/**
2 * [1704] Determine if String Halves Are Alike
3 *
4 * You are given a string s of even length. Split this string into two halves of equal lengths, and let a be the first half and b be the second half.
5 * Two strings are alike if they have the same number of vowels ('a', 'e', 'i', 'o', 'u', 'A', 'E', 'I', 'O', 'U'). Notice that s contains uppercase and lowercase letters.
6 * Return true if a and b are alike. Otherwise, return false.
7 *  
8 * Example 1:
9 * 
10 * Input: s = "book"
11 * Output: true
12 * Explanation: a = "b<u>o</u>" and b = "<u>o</u>k". a has 1 vowel and b has 1 vowel. Therefore, they are alike.
13 * 
14 * Example 2:
15 * 
16 * Input: s = "textbook"
17 * Output: false
18 * Explanation: a = "t<u>e</u>xt" and b = "b<u>oo</u>k". a has 1 vowel whereas b has 2. Therefore, they are not alike.
19 * Notice that the vowel o is counted twice.
20 * 
21 *  
22 * Constraints:
23 * 
24 * 	2 <= s.length <= 1000
25 * 	s.length is even.
26 * 	s consists of uppercase and lowercase letters.
27 *
