Codechef used to conduct ICPC mirror rounds of each regional, which were a great way to practice for upcoming regionals as a team. But for some reason it was not done previous year. I request @admin to conduct it this year
already two contests have been ended.
+1 to this, it will be really helpful.
At this point I just hope CodeChef is putting its effort into making good problems with proper statements and strong test data.
I consulted @admin about this sometime back. He said that while mirrors are not possible, replays would be done. Sorry, couldnt update you then because of exams.
