From a given set choose as many rectangles with a common side as possible.

Finally the Silver Challenge is here!

At Codility we help engineering leaders hire software developers and technical people into their teams. We’re committed to building a platform that provides equal opportunities to all developers, focussed on analysing technical skills in an unbiased way.

That’s why for us, the Silver Challenge is a little special. Once you’ve submitted your solution, you’ll be invited to complete a short demographics survey.

The results of this survey will be analysed by our research team anonymously for statistical purposes only. The findings will support our continued research into improving how we evaluate technical skills without bias, and will ensure we can keep building diverse developer community around the world.

Enjoy solving this Challenge, and we appreciate you taking the time to complete the survey!

Good luck, Team Codility
