Remember the rules for this are
- Try to use only the information given up to this point in this book.
- Try not to give up until you've given it a solid attempt
You are extremely likely to be quizzed on for loops on any standardized tests,
so these challenges are going to include a lot of repetition and sometimes a tricky
