Kdb+ Mastermind Challenge
4 Oct 2017
The Kx Community NYC Meetup recently competed in a Mastermind coding competition moderated by expert kdb+ programmer Nick Psaris, author of the book "Q Tips: Fast, Scalable and Maintainable Kdb+." The top four solutions were notable for the completely different approaches they took. Mastermind is a popular code-breaking game introduced in 1975 that pits a “codemaker” against a “codebreaker.” The “code,” represented by four pegs chosen from a universe of 6 colors, is picked by the “codemaker.” The “codebreaker” continually makes 4-peg guesses and is told by the “codemaker” how many are the correct color in the correct position, and how many are the correct color in the wrong position.
