I have been doing competitive programming for 5 months now and started with codeforces a couple of months ago. I have been practicing questions from UVA Online Judge which consists of the questions from the book Competitive programming 3 bye Steven Halim. But the format of those questions are not like that in codeforces or codechef, they are a bit different and sometimes a lot confusing too and I don't have any access to editorials, so its a little difficult to follow that, I have also recently learned about CSES problem set.I wanted to know which is better, should I switch to CSES? How are the questions of CSES?
