Second-Ever CS50x Coding Contest
On Friday the 13th (boo!) of January 2017 began the second-ever CS50x Coding Contest, the much-awaited sequel to 2016’s first-ever, thanks to our friends at HackerRank. This epic weekend of code invited CS50x students around the world to form teams with 0, 1, 2, or 3 classmates (or friends) and tackle a set of 10 programming challenges, all of them written (for Fall 2016’s on-campus coding contest) by CS50’s own undergraduate staff.
Just as the first contest was announced with some fanfare, thanks to CS50’s production team:
So was the second!
Notice how CS50’s saloon makes an appearance in the latest.
Teams had 3 days to tackle the contest’s 10 challenges, each of which had to be implemented in C:
- Ordinary Ordinals, by Chris Auclair
- Title Case, by Benjamin Doran
- Be Our Guest, by Brian Yu
- Parsum, by Francisco Trujillo
- AABB Collision Detection, by Thomas Lively
- Cats Eat Fish, by Annie Chen
- Framed, by Christopher Chen
- Six Degrees of Bill Gates, by Walter Martin
- When in Rome, by Zack Chauvin
- Feeding Garfield, by George Zhang
(Click the Editorial tab on each challenge’s page to see a sample solution.)
Students from all over the world registered, from 80 countries in total, with the most students from:
- India, with 207 students
- United States, with 124 students
- Egypt, with 22 students
- Brazil, with 17 students
- Canada, with 17 students
- Algeria, with 14 students
- United Kingdom, with 14 teams

Though apparently only Algeria took photos!
