Emotional Chatbot |2|
~~~~~~~~~~~~~~~~~~~~~

| You want to create a chatbot that can understand when the human on the
  other end is sad. So you want to be able to recognize texts like
  ``"uhu", "uhuh","uhuhu"...``.
| Write a program that prints ``"Are you sad, hooman?"`` to the screen
  if the given input is in the form :math:`(\texttt{uh})^n` or
  :math:`(\texttt{uh})^n \texttt{u}` where exponent :math:`n` denotes
  :math:`n` times repetition of the characters in the parantheses.
  Otherwise, the program should print ``"I am so sad, hooman."``.
