Problem Statement

Elly is constantly learning new languages. Sometimes she has difficulties with the pronunciation, mainly caused by excessive presence of vowels over consonants or vice-versa in the words. She considers a word easy to pronounce if it has equal number of vowels and consonants. As you can see yourself, words like "allure", "voulez", "vorliebe", and "amor" are relatively easy to say out loud, unlike, for example, "wrath", "ecoeurement", "abneigung", or "odiar".

You are given the words that Elly has learned this week in the String[] words. Count how many of them are "easy" to pronounce (i.e. have equal number of vowels and consonants).
