Title: Visual Crypto
Post by Friberg on Jul 31^st, 2003, 6:44pm

So the first part:
10000010000010000010001010000010011000100
10000010000010000011011010000011001000100
11111010000011110010001011111010001011111
11111011111011111010001011111010001000100
11110010000011110010101011110010101000100

And the second: 3, 2, 5, 1, 4

Hm, looks like an elementary puzzle that the casual riddler should have no problem to solve.

I don't think it's really "hard".

Never mind. Opinions on the difficulty of riddles vary quite often.

Mmkay... but do you know any solution to this one? Thanks..

Yes, I do. Part of my first post is a hint. Well, if not to the solution then at least to the fact that I solved it.

Try to [hide]relate the range of numbers in the second part to the first part[/hide].
Hope that leads you somewhere.

Nope.. still not got it :'(

How about this: [hide]The length of each line in the first part is 41. But that's not of much help[/hide].

I'll try. Although I already gave hints number one and two in my previous posts, if you will.

Hint: [hide]Think of the second part somehow indexing elements of the first[/hide].

Way to the answer: [hide]Rearrange the lines of the first part according to the numbers given in the second. So the third line becomes the first, the second remains second, the fifth becomes third and so on. Now read[/hide].

You're welcome. :)

I haven't seen such a coding either, by the way. As it is, it's a bit too clear, I think. One could probably use it (at school, for example :D) if one somehow codes (or safely communicates) the second part and breaks the formatting of the first, letting the intended recipient know the length of the lines.
