Mary owns Mighty Mary's Smash Hut, a boxing school in Rochester Hills. She has a special offer, an intro to face smashing course, at a special price. Even cheaper if you have a Groupon. Write a program to compute the price of an order.

Here's some I/O.

  • How many people (1 to 4)? some
  • Sorry, you must enter a whole number.
  • How many people (1 to 4)? 3.65
  • Sorry, you must enter a whole number.
  • How many people (1 to 4)? 4444
  • Sorry, please enter a number from 1 to 4.
  • How many people (1 to 4)? 3
  • Do you have a groupon (Y/N)? not sure
  • Please enter Y or N.
  • Do you have a groupon (Y/N)? y
  • Do you want to rent headgear (Y/N)? maybe
  • Please enter Y or N.
  • Do you want to rent headgear (Y/N)? y
  • Do you want to rent body pads (Y/N)? perhaps
  • Please enter Y or N.
  • Do you want to rent body pads (Y/N)? n
  • Price: 357
  • You should rent protective gear!

The price is computed as follows:

  • The base price per person is $99 with a Groupon, or $250 without one.
  • Headgear rental costs $20 per person, whether or not there is a Groupon.
  • Body pads rental cost $30 per person, whether or not there is a Groupon.

For all input, keep asking until the user enters valid values.

  • People count must be an int from 1 to 4.
  • Other inputs should be y or n. Strip spaces, and allow upper- and lowercase.

If the user says they don't want headgear and/or body pads (either or both), show a warning after the price.

Write a reusable function to get one Y/N input at a time. Call it three times.

Upload a zip of your project folder. The usual coding standards apply.
