Yep. Thank you. Fixed now.

i was afraid this might be unclear. I'll reword it when i get a free minute. thanks again

Thank you. Should be fixed now.

That's specifically part of the instructions. "All alpha characters will be treated as upper case"

Retrun is totally a word

Thanks... should be fixed now (hopefully)

Thanks... Fixed

Wow. That was quite an oversight. Hopefully it's fixed now. Thanks

Sorry. I was worried that this might cause confusion. What I meant by "All other characters" is the following:

Each character in the unencoded message will be sent to exactly one friend. So, in the example "You are all sexy" (with 3 friends), 'Y' goes to friend 1, 'o' goes to friend 2, 'u' goes to friend 3, ' ' goes to friend 1, 'a' goes to friend 2... etc.

The dashes represent, for each friend, a character that was sent to a different friend. That way, friend 3 knows that there are 2 characters before 'u' because his letter starts "--u".

I hope that helps.

Added random testcases

Oh... I see. That sucks. Why would people want to cheat? That defeats the entire purpose of this site.
Thanks for explaining. I'll revisit when I get a chance.

done. thanks

Excuse my ignorance, but what exactly do you mean by random tests?

Why? (this is a serious question... not me being a jerk)

I didn't see any reason not to limit it. I didn't want people to spend all their time worrying about arithmetic limits of languages.
