                       binary numbers.
                    b.   In a puzzle challenge, Ravi provided Maya with the number 23 and mentioned
                       that  it was written  in octal  (base-8). To solve the challenge, Maya  needs  to
                       convert this octal number into its decimal equivalent. What is the decimal value
                       of the number Ravi gave her?
