The Great Code Off 2021

Start date: March 27, 2021, 5 p.m. UTC
Count the number of cakes consisting of K different layers in the order 1, 2, ..., K that will be created after a sequence of operations of putting a layer on some interval.

Do you have what it bakes to win The Great Code Off?

The first 3 developers to solve the challenge perfectly in the least amount of time will be added to the Codility Hall of Fame, winning a package of swag and of course, bragging rights. Winner #1 would also get The Python Cookbook to further prove their skills.

Once the Great Code Off has ended (on April 10th), you will still be able to take the challenge, and gain certificates, but will no longer be in the running for prizes.

This Challenge is not a piece of cake, so good luck solving it!
