National Coding Week

Find the alphabetically largest string that can be obtained by performing some substitutions.

Let us celebrate National Coding Week with a new challenge!

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 some great prizes listed below:

1st place - 1:1 AMA session with our CTO - Snir Yarom

2nd place - donation to the charity/organization of your choice, that helps people learn to code

3rd place - a coding book of your choice

Coding can be a step towards a new future, our mission is not only to help hire the best talent there is but also to encourage people to learn and thrive!

Once The National Coding Week challenge has ended (on September 25th), you will still be able to take the challenge, and gain certificates, but will no longer be in the running for prizes.

Good luck solving this challenge!
