Just saying…if the authors of the problems on long/short contests submit an explanation along with the problems there wouldn’t be any delays. It’d be great if their explanation included the following :
Complete description of the approach used.
And hopefully the real-world scenarios where we might encounter such problems, because simply solving the problems without realizing the applications doesn’t make any sense.
And of course after publishing others may share different/better methods to solve, if any. I guess this could be implemented by CodeChef, I mean is it not feasible? By the time editorials are uploaded, the spirit that is present during the contest will almost vanish, so the sooner the better
