Hi everyone, I'm looking for problems involving RSQ static. I know it's a very simple technic, but I need it for a class, to give them some problems to practice. I've solved a lot of problems with it, but I've never classified them, and weirdly I can't find any of them googling. Until now I have this two: http://codeforces.com/problemset/problem/313/B http://coj.uci.cu/24h/problem.xhtml?abb=2111 If someone has some others, from any judge, I'll appreciate it. Thanks!
