The annual programming contest is back in its fourth year, starting Friday, November 6. RunCode is a non-profit organization staffed by volunteers who work in their spare time and focuses on providing educational opportunities for programmers and infosec people. The online event enables programmers of all experience levels to tackle a wide variety of challenges using any of the 14 supported programming languages.

This year the theme of the competition is “anything related to the internet”, which means that most of the challenges will have something to do with websites; although the “something” can vary quite drastically, from user interaction to server log analysis. The event has over 30 available challenges, grouped into easy, medium, and hard, for participants to find and upload solutions to.

For each challenge, participants are provided with a problem description, sample dataset, and expected output to clarify the desired order and format. Competitors are expected to generate more test data themselves and thoroughly verify the correctness of their code against all corner cases they can think of; solutions that have only been tested against the sample data provided are unlikely to pass the challenge. Uploaded code runs in a Docker container in a sandbox and the output is tested for correctness.

Amazon Gift Cards ($100, $200, $300, $400, and $500) will be awarded to this year’s top 5 winners. The event begins Friday, November 6 at 4:00 PM EST and runs through Monday, November 9 at 8:00 AM EST. Interested coders and future coders can sign up at, which is a very different registration from the one on the main site, which allows you to view challenges and try to solve them whenever you want. Please.
