We are looking for tutorials that are easy to follow and give intuition about the algorithm. A lot of online videos are one hour long lectures on the algorithm, when its quite easy to understand the algorithm (without dumbing it down in any way) in 5 minutes. If you encounter such videos or simple tutorials submit it here. We are looking for tutorials on beginner concepts as well as advanced ones going well beyond IOI syllabus.
