Counting Vowels in Substrings Using Positional Occurrence

  1. Initialize a variable total_vowels to 0 to keep track of the total count of vowels in all substrings.
  2. Iterate over each character in the string with its index i.
  3. Check if the current character is a vowel.
  4. If it is a vowel, calculate the number of substrings that include this vowel using the formula (i + 1) * (length of the string - i).
