Project Euler Forum

I know it sounds stupid, but could somebody have a look into it?

First I solved it in erlang. Then with paper and pencil, then downloaded a few solutions from the net. All of them gave the same result. Also, someone shown me his solution when I entered the result there. So I am pretty sure that my solution is OK. But still, it was not accepted as such.

Could you PM me your answer, so I can check if it's right?

Why doesn't he share his solutions on the PE forums..?

He does, at least sometimes (I found a post from him in the first thread I looked). He just wnats an extra opportunity to discuss solutions.
Also, he doesn't give away the answers or his code on the site directly, you have to provide the correct answer to get readable code.
Perhaps, with a good code breaker you could unscramble the garbage displayed upon a wrong answer, unless he then displays random junk.
Anyway, he took precautions to only let people who solved the problems discuss the algorithms, I find that recommendable.
Edit: Though I just learned that apparently the site's protection isn't too good, pity.

There was a site with encrypted solutions, which I cracked as a sort of meta-Euler problem. (All the plaintexts started with the same 16 characters But I learned a bit of javascript at least.) It doesn't seem to be up now, though, so I guess you're talking about a different one.
