Hi everybody!

I'm trying to solve this usaco GOLD problem. I've tryed somehow to think and solve it with suffix automata but i couldn't. Now trying to read solution but can't get it. I don't understand about which graph talking there. Also, it uses trie and i have never written trie before.

Does anyone have any idea to solve this problem using suffix automata? Or if it's impossible with suffix automata can anyone share their ideas about this problem ?

Hello to every programmers!

I solved problems of one competition and I can't send these problems to any website. I have tests of problems. Also I have tester but I'm using Linux and tester is not working in Linux because testers format is ".exe" and ".exe" is not working in Linux. How can I check my problem with tests? Can you please help?

I heard that there're some websites that we can add problems and tests there and we can send our solution and check it.. but I forgot name of that website.. Does someone knows what was that website or can someone give some other advice for checking my problems?

Thanks for help and sorry if my English is bad.

I sent problem C from previous contest but it gave "Judgement failed". Also I looked to status and saw that everyone getting "Judgement failed"..

What does that mean and if there is any problem admin please can you fix it?

Thanks!

Hi everybody! Happy "Navruz" and Happy "Tajik New Year" to everybody!!! "Navruz" means new day, it is believed that it brings, new life, happiness and fun to our lives. It is very long history to tell why and how it was and it is celebrated,but you can read about "Navruz" here in wikipedia -> http://en.wikipedia.org/wiki/Nowruz.

In Tajikistan we are celebrating "Navruz" and it's also our New Year. We celebrate "Navruz" with our national foods that we are preparing them only in "Navruz".For example "Sumalak". "Sumalak" is the ancient and one of the truly national dish of Tajiks that is cooked only for "Navruz"! It takes exactly one week for preparing it! 6 days for growing wheat and one whole day for cooking! Here is the photo of "Sumalak".

Again Happy Navruz and Happy Tajik New Year:)
