Ccc 2012

[crossley7]

saltpro, hit me up on fb and I will send you the problems. I have my copy and perfect solutions for 4 of them.

[A.J]

I'm glad most of you found the contest enjoyable and/or easy. I must agree that the contest was easier than most years, however I don't think that the cutoff will be close to perfect (maybe mid to high 60's). Please refrain from discussing the solutions for another day or so. I can post a copy of the contest after a couple of days (if people want this).

[crossley7]

Crossing my fingers that it is low-mid 60's so I can make it on. Either way, looking forward to seeing other solutions for the problems (specifically 3,4,5)

S3, i could not find the correct base value for 500, some of the values worked but 500 didnt.

[NeilV]

Yeah I finished S1,S2,S3, and S5 within an hour. Then I spend a solid 2 hours on S4 and still didn't figure it out. But very shortly afterwards I came up with a solution that would have gotten at least 12/15, possibly 15. The frustrating part is that when I implemented this new solution, 90% of my code was copied and pasted from my solution during the contest.
Anyway, final score is 63.

Any idea what's the Max execution time allowed?

Also can we talk about solutions now?

[danc]

max execution time is 60 seconds...

My script for 4 gets it after 48 sec for n=8 on cpython on my computer ... 16 sec on pypy. Given that my marker 's laptop is probably slower... maybe u should convince her to get pypy?

[crossley7]

I ended up with 66 and probably still wait to comment on solutions. I think AJ will have an idea of when we can start discussing them and will let us know when that is the case

It doesn't really matter, as every program with an unofficial score of at least 40 gets remarked on the same computer for the official score.

Oh yeah!!!! I got perfect 75~
Isn't 1 min of execution time too long?? The contests I have participated before mostly had a time limit of 1 sec or 2 sec. It will take a lot of time to mark if everyone's program runs 1 min for each test case= =
At least my solution for Q4 gives answer well within 1s for n<8

Woah, congrats

This is my first computing contest....I got 60. Would that be enough to make it to honor roll or group 3?

I guess we won't know 'til the results come out, eh?

[crossley7]

It gives 1 min since some programs take very long to execute and it has some of the lowest restrictions of any contest I know of. Also, since it's your first contest, did you do Junior or Senior? If you did senior it would be some level of the honour role at the very least.

The unofficial solutions site has posted the test cases and problems, so I think we can freely discuss the problems now.

Anyway, from the test cases on the site, I have an unofficial score of 63. I hope this would somehow give me a rank of 20th... (though I highly doubt it)...

And yeah, I am very curious about how you guys solved #4.
