//3.2 Questions
//a. Our final code did not compile and it had multiple errors because there was 
//still comments left over and the variables were changed so it was missing variables

//b. Could not fix it so it still didnt run and it had the same errors

//c. We miscommunicated on where to change the code since we ran out of time
// every time someone had their turn so in the end we had a lot of comments left over
//and also still had some of the loops missing which made it so it failed to compile properly
