Playing with the full DEC
Posted: Sun Jun 12, 2016 2:58 am
Couldn't figure out the solution for a long time. But after a while I looked at the challenge with the fresh eyes! Based on the fact that every number starts with 00 01 or 02, I made a decision that numbers are independent (at least you probably shouldn't concatenate encoded ones), and started to search for some wierd 36bit systems on the web.
So with 'DEC' and '36bit' as the keywords, Radix-50 character encoding was something I found worth to check. Got 30,18,15,0 for the first number. My first assumption that it is "THE " was correct and I was happy so solve that just looking for A.K. on the book wiki page.
Still, found out that there are exist lots (ok, more that one is a lot) character sets for 40-character Radix-50 tables, so you should either guess correct shift for characters or find the right one.
Actually loved this encoding principle, as it packs non-(2^n) data pretty well.
After solving a challenge i'm surprised how few people succeeded!
