Niobium 2019

Start date: May 4, 2019, 5 p.m. UTC
A matrix of binary values is given. We can flip the values in selected columns. What is the maximum number of rows that we can obtain that contain all the same values?

Kicking off May is The Niobium Challenge, hosted by Codility.

Here at Codility, we help companies grow their dev teams by assessing their candidates’ technical skills online. We’re growing our team too - so if you’re interested in helping us refactor tech recruiting, check out our open positions.

Good luck solving this Challenge!
