def machine_guess():
    """
    Prompts the user to enter a number between 1 and 100 to act
    as the number which the machine must guess.

    Until the "secret" number is guessed correctly, repeatedly do the following:
    - Generate a random number between the best lower bound guessed so far
      (initially 1) and the best upper bound so far (initially 100) and
      `print` it to the user. For example, if the "secret" number is 50, and
      the machine has already guessed 25 and 75, then a random number should
      be generated between 26 and 74 (both inclusive).
   - Prompt the user to enter 'H' if the guessed number is too high, 'L'
     if the guessed number is too low, or 'C' if the guessed number is correct.
   - If `'C'` is entered, a victory message and the total number of gusses made
     should be printed and then the function should terminate.

    This function does not return anything.
