I met a girl and wow! it's like she's my muse (no, I am not an ancient Greek :) ). She inspired me to build an app that will have a simple riddle that will say
"Θελεις να βγουμε?" ("Do you want to go out with me?" in Greek).
I'm trying to think of a simple math equation that would result in +1, and then having the message be the greek letters that are one position before the letters in my message:
ηδκδθρ μω αβξτλδ?
where if you take the previous letter from the Greek Alphabet, the intended string will be revealed!
However, I am worried of how to hint to her to do this? I mean, I am in Computer Science and adding 1 from the ASCII code seems obvious to me, but she is not in CS. So how do I hint to her (without actually making it too easy) that the +1 means that she should take the previous letter for every letter in the given string?
If +1 is a bad choice, please suggest a new one!
