We partitioned the problem JADUGAR into two subproblems JADUGAR and JADUGAR2 (each subproblem will have the score 50 pts). Those who solved JADUGAR will have at least 50 pts. Duration of the contest will be extended by one day.
Be very careful!!
Why I can't submit JADUGAR2?
mgch kingofnumbers
what is it telling you? I can see people are normally submitting solutions to this problem.
Sorry, but it is fixed now. Submit button was disappeared this morning, then it came back again.
I think Judging is taking very long or is completely down. I am waiting since 10 mins for a verdict
When will you write the "official" editorial for the contest?
They are already out. They were out 40 minutes ago :/

thanks very much mgch !
For CUTPLANT, can someone explain editorialist's O(n) approach in more detail? I didn't get it. Thanks in advance.
Hey dear, its always better to ask this question at editorialist's page itself. I make sure to periodically monitor that forum to answer such queries. Can you brief on till where you understood?
