Due to the appearance of IOI archive on Codeforces (https://codeforces.com/blog/entry/104593) the problem of IOI style contests becomes more relevant. As many of us know, on Codeforces problems' subtasks are not merged in any way, and the score of certain task is the maximum score among all submissions for this task. So it would be really great if Codeforces fix that problem)
