National Coding Week 2022

Start date: Sept. 10, 2022, 5 p.m. UTC
Given a tree graph, find the number of pairs of vertices whose distance is odd.

** Let’s celebrate National Coding Week with a new challenge! **

The first three developers to correctly solve the challenge in the least amount of time from the start of the challenge will be added to the Codility Hall of Fame, winning some great prizes listed below:

1st place - 1 hour 1:1 AMA session with our Staff Architect, Andrew Fiorillo

2nd place - A $100 donation made to the coding charity/organization of your choice

3rd place - A coding book of your choice

Coding can be a step toward a new future, and 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 24th, 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!
