Work in pair.
It’s not a contest.
Open to any programming language.
Code and test directly on the browser.
Solve 3 self-contained problems.
Find, discuss and understand solutions.
People arrive and meet. The Coding Gym trainer gives them a warm welcome!
People pair off, agree on a programming language and seat side by side.
The attendees work in pair on a coding challenge: they can code and try solutions directly on the browser. In the meantime, the trainer peeks at what they are doing and gives hints if someone gets stuck.
The trainer opens a discussion on the solutions found and some volounteers explain theirs. People scrutinize tradeoffs and decisions taken. Then, the trainer changes some constraints of the problem and people discuss about the implications.
