Yer a coder, Harry!
Please remember that you aren’t allowed to use magic outside of Hogwarts, so to win this challenge, you’ll need to rely only on your coding skills.
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 Netflix gift card so that you can rewatch your favorite movie series - on us!
Once the Pair a Coder challenge has ended (on February 5th), you will still be able to take the challenge and gain certificates, but you will no longer be in the running for prizes.
Good luck solving this challenge! Mischief managed!
