Hi everyone,
We are proud to present the third annual Spring Coding Bowl, a 3-hour, 5-problem competition open to all high school students. The contest will run from 12:00am on Saturday, May 28 to 11:59pm on Wednesday, June 1 (Eastern Daylight Time).
To register, please follow the instructions on our official contest webpage. The contest will be hosted here on DMOJ, and you will have to submit your personal information when joining this organization. Please ensure that you register before 6:00pm May 27.
An official honour roll will be published on the contest page, the top scorers will be named as "Coders of the Year", and schools will be ranked by the sum of the three highest scores from each school. As such, please be sure to tell other students in your school to participate (perhaps get your school's coding club involved)!
If you would like to prepare, you can try to solve last year's problems here on DMOJ.
Good luck to all participants!
