Minor Changes To Project Riddles

[CodeJunior01]

I added 1 more riddle. I added a few more comments, to code, so just reading the comments you'll be able to understand what each block of code is doing, this is my first attempt at working on projects and just wanting to see and understand the whole process of working with people on github and how people can collaborate on projects. I intend to continue from here on out, with other github projects, and working on actual coding. Thanks.
