Добро пожаловать на 2014-2015 CT S02E10: Codeforces Trainings Season 2 Episode 10 - 2014 Amirkabir University of Technology Annual Programming Contest (AUT APC 14). Продолжительность тренировки — 5 часов. Тренировка открыта как для команд, так и для индивидуальных участников. После ее окончания вы можете дорешивать задачи тренировки или поучаствовать в ней виртуально, если не смогли принять участие одновременно со всеми. Пожалуйста, участвуйте в тренировке честно.
Так как это тренировка, то возможно набор задач будет расширен, если для значительного количества участников он окажется простым.
Условия задач будут на английском языке, ведь мы же готовимся к ACM-ICPC!
Удачи!
Nice Picture ;)
Are the problems past years or this year?
This year.
Thx for the contest, this weekend the regional contest in China will start, I think it is a good chance to practice and warm up for me!
I am facing a weird problem. I registered for the contest. Then right before the contest, my teammate notified me that our team has registered for the contest.
After a while, when I submitted, my submission started showing separately from my team. This didn't happen to my team members. Only to me. I immediately mailed them my solution and they submitted those from their pc.
It is kind of tiring to send solutions back and forth. Not to mention it is against CF policy. How do I switch into team mode? Or did this anomaly occur cause I registered separately?
My codes: A, B, C, D, G, H, I, J.
Also, in case anyone wanted it, test 1 for problem E (value it, it took about 20 submits in coach mode to get).
Thanks for your hard work! Now at least we have something to debug for E.
Can you please explain the solution of 2nd testcase of Problem B?
Shouldn't the answer be 7? (ab,aB,aA,bB,bA,BA,abB)
Solution for A, B, C, D, G, H, I, J
In problem K first test is not sample test case.
and tests or statement is unclear. is 25th test two points have same x and y, but statement says "The points are different, but clearly some points maybe collinear". Jury's answer for that test is 4 and i dont understand how to get it.
