No License

[JStephens33]

Hi, how are you? I have been looking at your code recently, and I would like to upload some of my own exercises which have been derived from a variety of your programs. The format would look similar to code academy and hacker rank. However, individuals would copy and paste the code that I upload, and fill in the blanks missing in the program in order to get it to work. Each uploaded code would basically function like a tutorial.
However, I have noticed that you do not have a license. This means that I am unable to use anything that has been derived from your code. I am writing to you hoping that you respond and that you allow me to upload code onto github that has been derived from your programs.

Thank you for your time.
