Determine if String Halves Are Alike
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
truea = "bo" and b = "ok"; each has 1 vowel, so they are alike.
Example 2
Input
s = "textbook"Output
falsea = "text" has 1 vowel whereas b = "book" has 2, so they are not alike.
Constraints
- 2 <= s.length <= 1000
- s.length is even.
- s consists of uppercase and lowercase letters.
