I would, but I'm not as pr0 as you guys and I would feel left out. :<

Anyhow, just got 20 and 48. ^_^

EDIT: And 18! :razz:

I don't know about the other guys, but I'm willing to help anyone who is having trouble with problems I know how to do.

If you ever want to talk to me on irc, just type any form of my name and it'll ping me.

359 is going to be REALLY tough. 27 minutes in and nobody has solved yet wtf ??

EDIT: GET OWNED !!!!!!!!!!!!!!!

 FFR4EVA_00 11-19-2011 08:36 PM

I COMPLETELY forgot about 359 happening today

 Reincarnate 11-19-2011 09:32 PM

w00t

 LongGone 11-19-2011 09:41 PM

I obtained the general formula for 359 but idk how to code/program (and 358 too)

):

 Reincarnate 11-19-2011 10:19 PM

Learn either Python or C++ (Python is my baby although Ruby is leonid's) -- both come in handy depending on the problem.

C++ is better for speed (if I know the problem is going to require ugly bruteforce), but stuff like Python/Ruby is easy to script with.

 Reincarnate 11-22-2011 08:05 PM

fffff some of these are getting pretty tough

 Reincarnate 11-27-2011 01:32 AM

welp

360 is pretty much 353 on steroids

 leonid 11-27-2011 02:23 AM

360 ;_;

Gosh, can anybody give any hint about 360? I made an optimized bruteforce and it's still slow :( Anything I can do is prove that answer is divisible by 6 :(
357,358 and 359 was much simpler.

well this looks like fun :D

now I'm level 8 :') (200 problems solved)

Congrats! I'd have more problems solved, if only I could stop coming up with algorithms that takes O(2^n) time. >_<

 Reincarnate 12-6-2011 04:09 PM

awwww yeah
