CodeChef August Lunchtime starts in an hour. I'm the author of all editorials to the problem set and I can assure you that all the problems are interesting to solve. There is one cakewalk problem and 3 harder ones of various difficulties, so anyone should be pleased, especially those ones interested in graph theory
All the editorials will be available after the contest here: https://discuss.codechef.com/tags/ltime39
See you on leaderboards!
