As soon as you post answer that pass the tester file I'll rate asap

New rule: no use of global variables (sharing data between functions not via arguments). Up to 10% penalty. What can I use? You may only use the following things. We are quite unlikely to add to the list, but note there are some useful things that weren't available earlier in the semester. If you use something disallowed, it's not an honor code violation, you just won't get points for some or all of that function (still not fun!). Restrictions no modules may be imported.
