The Coder of Rivia

Start date: Aug. 7, 2021, 5 p.m. UTC
Given a 3x3 matrix, find the nearest matrix, the sum of whose elements in each row and column is equal.

Toss a coin to your Coder, O’ Valley of Plenty!

The first three programmers to prevail over this challenge in the least amount of time will be added to the Codility Hall of Fame, winning the Netflix gift cards and of course, bragging rights across the Continent.

Once The Coder of Rivia challenge has ended (on August 21st), you will still be able to take the challenge, and gain certificates, but will no longer be in the running for prizes.

Good luck on your path to victory!
