The chatbot had already solved the challenge, so I decided to test-run the code it suggested as the solution, and it worked. For the input string "blessedtechie":
[*]* The vowels are 'e', 'e','e','i' and 'e'.
[*]* The function correctly counts these vowels and returns 5.
This function will work correctly for any input consisting of lowercase letters and/or spaces.
