Cemetech Contest #15, Challenge 3
Published by KermMartian on December 30, 2015 at 11:41:47 AM CST | Discuss this article (70)

For the past two Tuesdays, we have announced increasingly difficult challenges as part of Cemetech Contest #15: Crypto Golfing. This five-part contest tasks programmers with solving cryptography puzzles, then creating programs that can decode messages in the cipher used for each challenge. We received an overwhelming number of entries written in many different calculator and computer languages for Challenges 1 and 2, although the field has started to thin. Since another Tuesday is upon us, Challenge 3 of Cemetech Contest #15 is here! If you haven't started entering the contest yet or if you haven't completed one of the existing challenges, you still have time, and the only thing you'll lose is the (up to) 5 bonus points you get by submitting your solutions quickly. Challenge 3 is the last pure-text cipher, and if you're still stuck with it on Friday, we'll be publishing an extra hint on Friday afternoon at 5pm, Eastern Time.

Challenge 3: OEEJCYKL WK AU LTMY L WXOJWN

Good luck! To repeat the incentive, besides prestige and glory: a TI-Nspire CX and a TI-84 Plus C Silver Edition await the top two contestants.
