KTH Challenge 2014 online contest
By lukasP, 11 years ago, In English

We organize a programming contest at KTH in Stockholm next Sunday, April 13, 11:00 – 15:00 CEST.

Right now you can create a Kattis account and solve some warm up problems from last year. The problems in the real contest will be of similar character and difficulty as last year. We will reveal the URL of the contest system before the contest. The allowed languages are C/C++, Java, Python, C# and Go, but Python might be too slow for some problems.

For people going to the World Finals this is a great opportunity to try out the Kattis contest system.

Btw, the contest also has an on-site competition happening at KTH in Stockholm, but only for university and high school students.

I hope you will have fun!

Thanks for organizing this contest!

Unfortunately, it seems that the newly announced Codeforces Round #241 clashes with KTH Challenge...

    Problem H.

    Why in optimal solution z will have z = x[i] - y[i] mod m[i] for some i?

      If this is not true, then you can take z-1 instead and get a lower solution, so z is not an optimal solution.

Problem E is very interesting! Again a problem that solution uses randomness written by Per Austrin :)
