► LeetCode 1704. Determine if String Halves Are Alike: https://leetcode.com/problems/determine-if-string-halves-are-alike/

► Problem açıklaması:

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.

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.

Return true if a and b are alike. Otherwise, return false.

Example 1:

Input: s = “book”

Output: true

Explanation: a = “bo” and b = “ok”. a has 1 vowel and b has 1 vowel. Therefore, they are alike.

Example 2:

Input: s = “textbook”

Output: false

Explanation: a = “text” and b = “book”. a has 1 vowel whereas b has 2. Therefore, they are not alike. Notice that the vowel o is counted twice.

Example 3:

Input: s = “MerryChristmas”

Output: false

Example 4:

Input: s = “AbCdEfGh”

Output: true


2 <= s.length <= 1000

s.length is even.

s consists of uppercase and lowercase letters.
