Carol of the Code

Start date: Dec. 3, 2022, 5 p.m. UTC
Given a sequence of squares, find the minimum number of rotations needed to obtain a pretty sequence.

Do you wanna build a software?

The festive season is approaching which means spending more time outside setting up decorations or building snowmen. But what better way to spend a chilly evening than having a cup of hot chocolate and building some great software?

The first 3 developers to solve the challenge perfectly in the least amount of time from the start of the challenge will be added to the Codility Hall of Fame and win a $25 Amazon gift card. Feel free to spend it on gifts for yourself and your loved ones.

Once the Carol of the Code challenge has ended on December 17th, you will still be able to take the challenge and gain certificates but will no longer be in the running for prizes.

We wish you a joyous holiday season and a Happy New Year, and of course, good luck with the challenge!
