Practice
These are some practice and for fun problems that I have done. I hope to cover each problem in a few languages, mainly ones I am interested in at the moment. Most of these have come from old textbooks or just things I thought would be interesting to mess around with, contact me a leave me some suggestions for stuff to try out.All source for these is available on Github, feel free to fork them!

Practice 1
Write a program to determine all pairs of positive integers (a,b) such that a < b < 1000 and (a^{2}+b^{2}+1)/(ab) is an Integer.
