PureBASIC Challenge PB!

Ok, this is going along the same lines as the python challenge, but this one is focused in pb

This requires you to rearrange the program to make the values needed.
I think this one is pretty hard, and i made it quiet quick so might be easier than i think.

Tell me how you did :)


P.S. This code will look pretty confusing at first, but basicly all you need to do is change the value of a and b at the top to make it compute the correct value!

Code: Select all

a = 0
b = 0

t = a : t-t+t-t+t+t-t+t-t+t-t+t+t+t-t-t+t+t+t+t-t-t+t+t-t-t+t+t-t-t+t+t-t+t-t-t+t+t-t+t+t-t-t+t+t+t+t+t+t+t+t+t-t+t-t+t+t+t+t+t+t+t+t+t+t-t+t-t-t-t+t-t+t-t+t+t+t+t-t+t+t+t+t+t+t+t-t+t+t+t+t+t-t-t+t-t+t+t+t+t+t+t+t+t+t+t+t+t-t+t+t-t-t-t+t+t+t-t-t-t+t+t+t+t+t+t+t-t+t+t-t+t+t-t+t+t+t-t+t+t+t+t-t+t+t+t+t+t-t-t-t-t+t+t-t+t+t+t+t+t+t-t+t+t+t+t+t-t-t+t+t+t-t-t+t+t-t+t+t+t+t+t-t+t+t+t-t+t+t-t-t+t+t-t+t+t+t+t-t+t+t+t-t+t+t-t+t-t-t+t-t+t-t+t-t-t+t+t+t+t-t-t-t+t-t+t-t-t+t-t-t-t+t-t-t+t+t-t-t+t-t+t+t-t-t+t-t+t+t-t-t+t+t-t+t+t-t-t+t+t-t+t+t-t+t+t+t+t-t+t-t+t+t+t+t+t+t+t+t+t+t+t-t+t-t-t+t+t-t+t-t+t-t-t-t-t+t+t-t+t+t+t+t+t-t+t+t+t+t+t+t+t+t-t+t-t+t+t+t+t-t+t-t+t+t+t+t-t-t+t+t+t+t+t-t+t+t+t-t-t+t+t+t-t+t+t+t+t-t-t+t+t+t+t+t+t+t+t+t+t+t-t+t+t+t+t+t+t+t+t-t+t+t+t+t-t-t+t+t+t+t-t+t-t-t+t-t-t+t+t-t+t-t-t-t+t+t+t+t-t+t+t+t+t+t-t+t+t-t+t+t+t+t-t-t-t+t-t-t-t-t-t+t-t+t+t-t+t+t-t-t+t+t+t+t-t+t-t-t+t-t-t+t+t+t-t-t+t-t+t+t+t-t+t+t+t-t-t+t-t+t+t+t+t-t-t+t-t+t+t+t-t-t+t+t+t-t+t-t+t-t+t+t+t+t-t+t+t+t+t-t-t+t+t+t+t+t+t+t+t-t-t-t-t+t+t+t+t+t-t+t-t+t+t+t+t+t-t-t+t+t-t-t+t+t+t+t+t+t+t+t+t-t-t-t+t-t+t-t+t+t-t+t+t-t+t+t+t+t+t+t+t-t-t-t+t-t+t+t+t+t+t+t+t-t+t-t+t-t+t+t+t+t-t-t-t+t+t-t-t-t+t-t+t+t+t-t+t+t+t+t+t+t+t+t+t-t-t+t-t+t-t+t+t+t+t+t-t+t+t+t-t+t+t+t+t+t-t-t-t-t+t-t-t+t+t+t-t+t+t-t+t-t+t-t+t+t-t-t-t-t-t+t+t-t+t-t-t-t+t-t+t+t+t+t+t+t+t-t+t+t+t+t-t+t-t-t+t+t-t+t-t+t-t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t-t-t+t+t-t-t+t+t+t+t-t+t+t+t+t-t+t-t+t-t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t+t-t+t+t-t-t+t-t-t+t+t+t-t-t+t+t+t-t+t+t-t+t-t+t+t-t-t-t-t+t+t+t-t+t+t-t+t+t+t+t+t+t+t-t-t+t-t+t-t-t+t+t-t+t+t+t+t+t+t+t+t-t+t+t+t+t-t+t+t+t+t+t+t-t+t-t-t+t+t+t+t-t+t+t+t-t-t+t+t+t+t-t+t+t-t-t+t-t+t-t+t-t-t+t-t-t-t+t+t-t-t+t+t+t+t-t-t+t-t+t+t+t+t+t-t-t+t+t+t+t-t+t+t-t+t-t+t+t-t+t+t+t-t-t+t+t+t+t+t-t+t+t+t-t-t-t-t+t+t+t+t+t+t+t-t+t-t+t+t-t+t-t+t+t+t+t+t-t-t-t+t-t+t+t+t+t-t+t+t+t-t+t+t+t-t+t-t+t+t+t-t+t+t+t+t-t+t-t+t+t-t-t+t+t+t+t-t+t+t-t+t-t+t+t-t+t+t-t+t+t-t-t-t+t+t+t+t+t-t+t+t+t+t-t+t+t+t+t+t+t-t+t+t+t+t-t-t+t+t+t+t-t-t+t+t+t-t+t+t

well done, paul you will get your cookie lol ;p

Looks like i need to make a harder one? ;)


How about one that to brute force (cough) will take your machine a few years, so you'd have to work back from the code :D

Again, well done ;p

Tried to make a loop to figure it out, but the result was a estimated working time on MANY days, several weeks at least.

Lol poor Bonne_den_kule, along the right lines :)

i'll tell you now, the number's do not go below 0 and not above 10000 :) hope that makes it easier!

Takes less time now, finish in a few minutes

Well, I'm not the best "cracker"... ;)

Ok 2 more winners

El_Choni
Bonne_den_kule

Well thats 4 people who have cracked it.

I have finished the next one and i will post it tommorow, this one is very hard, you can't brute force it, it would take for ever to brute force it.

This one will require you to reverse the encryption of the recived data and work out the beginning word. The program interacts with a server to stop any cheating ;)

Cya all tommorow!

I've also gotten possitive feed back from this challenge, im glad people like it and i will be making more during my free time :-)

Keep looking for news of the next challenge :lol:
