I've always wondered if you could fit 25 letters into a 5x5 grid such that the first 3 letters of each month are in there somewhere: diagonally, vertically, horizontally, backwards: The grid
Code:
FJGLD
EMUYE
BJANC
MPR
R
is pretty pathetic, because it is lacking sep, oct, and nov. I bet there is a way to brute force it in BASIC, but I don't have a clue how to start. Could you, the reader, post your code? I'd really like to have this question cleared up. I have gotten so irritatingly close, but still nothing. Thanks! |

Cool puzzle! Of course you *could* write a program to brute-force it in BASIC, but I doubt you'd have the patience (or the batteries) to wait for it to finish.

Answer:

GUARC
JMPDT
UAFEB
LYNCS
(It took my solver, written in C and running on my PC, about 40 minutes to come up with this. My PC is over a hundred times faster than a TI calculator. This is also the result of searching about 47% of the possible configurations, modulo rotations and reflections; the above might not be the only solution.)
Edit: Of course it isn't the only solution; there are at least 8 solutions, since you can switch the positions and orientations of FEB and DEC.
