Hello, World!

Welcome to the PEG Online Judge. This site was created by members of Woburn Collegiate Institute's Programming Enrichment Group as a resource for competitive programmers everywhere. We also run PEGWiki, a site for information and tutorials of algorithms.

Currently, we have 1149 problems, 482104 submissions, 277 analyses, and support for 15 languages.

If you are new here, register an account and get familiar with the judge by solving A plus B. Alternatively, you can try a random problem that you haven't solved.

Thank you for joining us in this year’s Woburn Challenge, new and returning participants alike!

Congratulations! These prizes will be distributed as Visa gift cards during the on-site finals in May to which all of the above winners are invited (more details to come later). Do not fret if you may not be able to make the final round in person – we will mail your prize to you afterwards. Remember that we will have many prizes in the remaining rounds of the year, so keep on practicing!

Woburn Challenge 2018 Online Round 1

by Alex on Jan 17, 2018 - 6:39:17 am UTC
Edit: The contest is over! Many thanks to all of you who participated. The questions have been cloned to the main judge. We will be posting prizewinners and analyses to all of the problems shortly. Check here, as well as our website periodically! Feel free to submit to them for practice while we work on publishing results and analyses. Note that questions are shared between divisions. In particular, submissions to all intermediate problems are not moved over and intermediate competitors will have to resubmit them on the main judge.

Problems: J1, J2, J3/I1, J4/I2, I3/S1, I4/S2, S3, S4

The Woburn Challenge is back for 2018! We've awarded thousands of dollars in prizes last year and are excited to do it again this year.

To be eligible for prizes, you must complete this year's registration form (see woburnchallenge.com/register) even if you have participated last year. If you have an existing PEG Judge username, you can continue using it.
