    1704 - Determine if String Halves Are Alike.

    Easy

    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.

    Constraints:

    • 2 <= s.length <= 1000
    • s.length is even.
    • s consists of uppercase and lowercase letters.
