    Maybe gift was made of rarely worn t-shirts so your fact more positive then negative.

      Yeah, mostly old and/or incorrect size T-shirts were used. Codeforces T-shirts are still in active circulation :-)

If my wife would have cut my two precious ICPC World Finals T-shirts, I'd cry for a week, definitely :).

    Good point!

    Most of my World Finals T-shirts are from my visits as a guest where I paid for the air tickets and hotel by myself, being essentially a tourist (no pun intended). So I don't have too big emotional connection to them.

      You made a pun by saying "no pun intended" :P

        That's not how it works. "No pun intended" means that you realize during writing that it can be understood as a pun, it's not a device for saying "there's a pun here".

          Yes, you are right. But while reading I was reading it normally but when I read "no pun intended", then it took my attention to pun, Hence it made pun for me:)

I looked at those problems from this Prime Contest and I recognized 2 problems that have already been on polish well-known competition — Algorithmic Engagements :P. Problem 7 (El Clasico) is a bit easier version of Termites from AE 2010 http://main.edu.pl/en/archive/pa/2010/ter and problem 11 (Kickout) is from AE 2012 http://main.edu.pl/en/archive/pa/2012/dwo (unfortunately — no english version). They are authored by the same person — Tomasz Idziaszek http://mirror.codeforces.com/profile/monsoon

Termites are one of the most known problems among polish contestants, when it was on AE, it was solved by a small group of contestants (if any) and when Kickout was on AE it was considered as a rather easy problem for last round of AE and was solved by many (30 or something) contestants including even me :P. But note that one round of AE consists of 2 hard and 2 easy problems and lasts 1,5 or 2 days, so it is understandable that when it was on a ACM-type contests it wasn't solved.

    Nice!

    El Clasico is harder than Termites since we can eat two planks at the same time, isn't it?

    Kickout is indeed the same — maybe that's where it came from? As far as I know problems from AE are sometimes reused at Russian trainings, so maybe it was unsolved when it was reused in this way. I agree it's not too difficult :-)

      Oh, you're right, I haven't read El Clasico statement carefully, Termites and El Clasico are different problems. And since I don't know solution to El Clasico, I can't judge which one is harder :P.
