Hi!
I'm glad to invite you to my first short contest on codechef.com on Sunday, 20th. (Check your time zone here.) I should also note that Anton_Lunyov help my a lot in preparing of the contest, thanks to him.
In order to take part in the contest you should be registrated on the site, you don't need separate registration for the contest. The competition will consist of 5 problems for 2.5 hours, by the standard ACM-ICPC rules.
After the contest you can discuss problems here and public all your wishes for the next contests.
Good Luck!
Lucky numbers again? I like them! :P
CodeChef = Lucky number :D
You can read the editorials here.
Setter's and Tester's solutions are not available.
UPD. Fixed.
While upsolving this contest, I found one Codechef feature: when you submit a problem and go to campus.codechef.com, in recent activity you see submission status. Difference with codechef.com is that if your solution is running you will also see some number in parentheses under running icon. Apparently, this is the number of test your solution is curently tested on(sometimes you can also see "running judge" with number too).
I also found out that your solution is actually tested against the whole testset even if it fails on some intermediate test. However, execution time will be only counted on first tests you passed plus the first test you failed (I mean time that will be shown to you if you get Wrong Answer). It's only my guess of course, but I strongly believe this is how their judge works.
