I see most of the questions in peer section have 0 solutions or 1 solutions. Are these questions extremely hard or wrong or people just don’t try to solve them? Where are the editorials in those questions?
Difficulty may vary (this section contains some easy problems too),these questions are from external contests like NCC2014,CDSN2014,… which are not organised by codechef.For editorials(of some problems) look for tags, there you can find a contest code, now go to that contest page using that code and there you may find editorial links!
