White does nothing to us using one of the MTdark themes.

i understand the sequence but could someone give me a hint on how to make a program ( in c ) to solve the next line to the n'th place?

thx!

...use strings rather than numbers?

fachamix · Post by **fachamix** » Thu Jun 28, 2007 4:48 pm

u have to use string instead of numbers ( or at least you yould treat the sequence as that)

is not hard to do it, you have to print "WHAT YOU SEE"

Even on the default theme, by monitor makes a clear distinction between the background and the white text.

Exactly, use a string and just count the number of consecutive repeated characters.

Here's a program in Haskell that generates the sequence, FWIW:

Code: Select all

import Data.List

next = concat . map writeOut . group
    where writeOut xs = show (length xs) ++ [head xs]
allSequence = iterate next "1"

allSequence is the whole sequence (an infinite list).

Haskell syntax has always bothered me intensely... What good is it for a language to be that concise if the code is just about write-only?

fachamix · Post by **fachamix** » Mon Jul 02, 2007 9:28 am

i agree with you Colonel Kernel

I find Haskell quite easy to read...it did take me a while to get used to, though.

Combuster · Post by **Combuster** » Mon Jul 02, 2007 10:40 am

It has probably to do with the fact that Haskell employs a totally different programming paradigm. If you have only done object-oriented programming then the workings of an haskell program is indeed like a big bloat of abracadabra.

From the people I've seen, it takes about three weeks to get an understanding of what is actually happening.

No, that's not it. I'm quite comfortable with functional programming. I think Haskell has exactly the opposite problem that Lisp has -- instead of too many parentheses, Haskell doesn't have nearly enough.
