title: How to split string into substrings of consecutive vowels?
body: <p>I have a long string of letters, I have to take all the substrings made by consecutive values and return the longest one. I had an idea to to it with regex but then I realized i never really touched regex before and I'm way over my head. Is there any way to do it without regex?</p>
  <p>I was thinking about (but I don't know if it's possible) creating a for loop that will add every consecutive vowel to internal counter and then when the next letter is consonant it will append all collected letters so far to the list. But I'm stuck on this a little bit, some tips might be helpful (I don't want outright answer).</p>
