Hello Codeforces!
It's been a long time since I posted a lesson in EDU section. Sorry about that, was quite busy managing my course on Youtube.
New lesson is about two pointers method.
What topics you want to learn next? I would prefer topics not covered in my Youtube course, something more specific for competetive programming. Any ideas?
More about EDU section you can read in this post.
Thanks to Stepavly and Supermagzzz for their help with lecture notes and testing problems.
Enjoy the lesson and good luck on the contests!
