    # We loop through each character of the string.

    # Here's why:
    #       We start at "B" in "BANANA", with 6 possible substrings:
    #       1. "BANANA"
    #       2. "BANAN"
    #       3. "BANA"
    #       4. "BAN"
    #       5. "BA"
    #       6. "B"
    #       Next is "A" in "BANANA", with 5 possible substrings:
    #       1. "ANANA"
    #       2. "ANAN"
    #       3. "ANA
    #       4. "AN"
    #       5. "A"
    # Luckily, the number of substrings = current substring length
    # Example: "BANANA" = 6 characters and "ANANA" = 5 characters.
    # Therefore, the current character count = points to add to the running score.
