ROT-ROT encryption algorithm
In my infinite boredom, I was inspired to write a useless "encryption" algorithm.
It is named ROT-ROT after the infinitely useful ROT-26. Your job is to write a function that can decrypt any message encrypted with the ROT-ROT encryption algorithm. There's the trick: you need to find out how it works before you can do anything with it. You can write the solution in any language, as long as I can read it and run it on my Linux box. The winners will get a free hug, cookie, AND gold star at the Championship Event in Atlanta, Georgia. All travel and related costs not inluded. The character set used in these examples: ['a','b','c','d','e','f','g','h','i','j','k','l','m ','n','o','p','q','r','s','t','u','v','w','x','y', 'z','_'] Example 1 (They are ni longer what?): wrvuukonfmqpzltzfypojqdcuurqck Example 2 (What is the meaning of life?): tovsrjqqihcqjuxwxa_eslburqidrqdihjxqgyb Example 3 (What is the airspeed velocity of an unladen swallow?): h_ggzyaetxjmdcyeiahlbaia_hzyyctaccpobsrvoesgkkx P.S. The solution is indeed deceivingly simple. P.P.S. I will probably post clues in the next week if nobody gets it. |

Who is good at numerical derivatives?

Re: ROT-ROT encryption algorithm
Numerical derivatives are a hint.
Another hint: A=0 and _=26 Maybe roboticists are not big on useless encryption... |
