   You are given a string, $str.

   Write a script to split the given string into two containing exactly
   same number of vowels and return true if you can otherwise false.

Example 1

Input: $str = "perl"
Ouput: false

Example 2

Input: $str = "book"
Ouput: true

Two possible strings "bo" and "ok" containing exactly one vowel each.
