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.

\n\n

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.

\n\n

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

\n\n

 

\n

Example 1:

\n\n
\nInput: s = "book"\nOutput: true\nExplanation: a = "bo" and b = "ok". a has 1 vowel and b has 1 vowel. Therefore, they are alike.\n
\n\n

Example 2:

\n\n
\nInput: s = "textbook"\nOutput: false\nExplanation: a = "text" and b = "book". a has 1 vowel whereas b has 2. Therefore, they are not alike.\nNotice that the vowel o is counted twice.\n
