Iterative Vowel Check

  1. Define a helper function isVowel that takes a character as input and returns True if the character is a vowel ('a', 'e', 'i', 'o', 'u'), otherwise False.
  2. Initialize a counter vowelCount to 0.
  3. Iterate over the words array from index left to right (inclusive).
  4. For each word, check if the first and last characters are vowels using the isVowel function.
  5. If both the first and last characters are vowels, increment vowelCount by 1.
  6. After the loop, return vowelCount as the result.
