KTH Challenge 2026

KTH Challenge is a programming competition designed for university and high school students. Anyone is welcome to compete though.

You compete individually trying to solve as many problems as possible within three hours. You may write solutions in a variety of common languages, including C++, Java, and Python. The test server automatically tests your program on a set of inputs, that are secret to you, and accepts your program if it produces the expected output within the allotted time. The problems test your programming skills and your ability to solve algorithmic problems.

KTH Challenge is the third contest in the Swedish Coding Cup 2026.
