----------------------------------- jimjim168 Tue Feb 23, 2010 5:31 am Here we go, CCC2010 discussion zone! ----------------------------------- Yeah, tomorrow in Beijing,China, we are going to have CCC2010! What a great thing! So here, anything about CCC is welcome! Here we go! Cheers~ :D --- P.S. something that we ought not to forget! 1. Close the file before the program exits. Or you would get no points. 2. Initalize the variables before using them. Very important. 3. Save your code as the competition goes on. 4. Double-check the name of your code, and the input file name as well. 5. Stay calm during the competition. 6. Eat some chocolates before the competition to get enough power. Your brain will be burning in the next three hours. At last, good luck to you all! You can make it! :D ----------------------------------- Insectoid Tue Feb 23, 2010 2:44 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- CCC in china? I thought it was a Canada-only competition. ----------------------------------- Shanethe13 Tue Feb 23, 2010 3:48 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Yep, the contest is also offered in China according to the CEMC website. Anyways, I just finished writing the Junior Contest about an hour ago, and through it went really well. I was able to finish all five problems within an hour and a half or so, so the rest of the time was just spent trying different test cases. I'm pretty confident on 1 - 3, and 5, but the wording for question 4 was a little odd, and I'm not sure if I did what it was asking. How did everyone else find it? ----------------------------------- cavetroll Tue Feb 23, 2010 3:59 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- I finished problems 1,2, and 4 on the senior contest. Unfortunately, I won't get any marks for number 4 because I forgot to remove the profiler when I submitted. I realized about 5 minutes after leaving the contest room. 3 and 5 I had the beginning of a solution for, but ran out of time before I could implement them. ----------------------------------- Insectoid Tue Feb 23, 2010 4:01 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- I'd like to mention that no complete or partial solutions or strategies should be posted until the deadline for teachers to send solutions in, as some people potentially have not done the contest yet due to inclement weather or whatever. ----------------------------------- konnetikut Tue Feb 23, 2010 4:15 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- I did the senior contest - finished problems 1, 2 and 3. Did not attempt 4 or 5. It's already been marked; I got 45/75. I know two juniors that got 72 and 75. ----------------------------------- saltpro15 Tue Feb 23, 2010 4:35 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- did S1 and S3, got angry, called it a day. ----------------------------------- Insectoid Tue Feb 23, 2010 4:40 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Not even S2? That one was easy! Even I got it and I had to half-relearn Ruby! ----------------------------------- saltpro15 Tue Feb 23, 2010 4:44 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- ah shut up : P I misread the problem statement, half coded a binary tree, then realized what it was asking. btw, I thought this year was supposed to be easier? that's the hardest one yet! ----------------------------------- Shah-Cuber Tue Feb 23, 2010 4:51 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- Agreed S1, S2, S3 ... No time for S4 & S5 Who else cried when they read S5? ----------------------------------- Kam Tue Feb 23, 2010 5:17 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- This was my first time attempting the senior problems (I've been doing the junior ones for the past two years) and I have to say.. it went pretty horrible for me lmao. S1 and S2 I got but i took way too long in completing them... S3 I had no clue where to start. I understood S4 and attempted to do it.. but I couldn't even get the input working correctly. S5 i looked at first page of the question, then fixed to next page, saw a tree diagram, got intimidated, and then went back to looking at S3 and S4 But I have to say, it was a good three hours. ----------------------------------- chengbin Tue Feb 23, 2010 5:52 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- I did the junior contest. I did J1,J2,J3, and a half baked J5. The first 2 questions was easy, J3 was substantially harder, but still doable without thinking first. I finished the first 3 questions in 45 minutes, and devoted the rest for J4 and J5. I only know Turing, and we're not even close to finishing everything. I couldn't do J4 because I didn't learn what's needed to do that question. J5 was brutal, it took almost an hour just to approach this program, how to start, and coming up with an algorithm. I finally figured it out that calculations can only bring you so far, and when you're a few spaces away you have to manually analyze the positions and come up with all the scenarios. I managed to get a half baked one working for a few spaces, but I took too long analyzing and finding out why some inputs wouldn't work. Even if I had the time I probably wouldn't bother. The code was pretty ugly and I got tired of it. ----------------------------------- Draymire Tue Feb 23, 2010 6:30 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- I just did the junior one today, i found it really easy, maybe i should have wrote the senior one. :) i finished problems 1-4 in about 1 hour and spent the next 2 hours working on problem 5. i had a program that worked for their test cases for problem 5 but not my own test cases. :( Anyways i think i will play around with the senior competition for fun. ----------------------------------- Shanethe13 Tue Feb 23, 2010 6:51 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Seems like it was the opposite with me. I found problem 5 of the junior section to be the easiest, and spent the most time on number 4. Well, easiest as compared to the last three. The first two will obviously be the easiest. ----------------------------------- chengbin Tue Feb 23, 2010 7:21 pm Re: RE:Here we go, CCC2010 discussion zone! ----------------------------------- Seems like it was the opposite with me. I found problem 5 of the junior section to be the easiest, and spent the most time on number 4. Well, easiest as compared to the last three. The first two will obviously be the easiest. Really? 3 was pretty darn easy. It just takes a while to code. No thought was required. But I do agree that 4 was harder than 5. ----------------------------------- Shanethe13 Tue Feb 23, 2010 7:33 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Well three itself was really easy, but I found that five was the easiest of the group. It was just basic recursion, whereas number three at least took some string manipulation. I think the biggest issue with four might have been the way it was worded. Edit: Then again, my main programming language is Haskell, so recursion is second-nature to me :P ----------------------------------- bbi5291 Tue Feb 23, 2010 8:11 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- Preliminary Senior results from my school.

Edit: Then again, my main programming language is Haskell, so recursion is second-nature to me :P In turing we have a convenient way to do question 3 without string manipulation (technically a programming error, but used as an advantage for the question). In turing if you don't put a * after a get variable statement, a space in an input will lead to the letters after the space to the next space to be the input for the next get statement. I didn't learn recursion, so question 5 was unbelievably painful to code. ----------------------------------- DtY Tue Feb 23, 2010 9:54 pm Re: RE:Here we go, CCC2010 discussion zone! ----------------------------------- In turing we have a convenient way to do question 3 without string manipulation (technically a programming error, but used as an advantage for the question).

Turing only reading up to a space isn't a programming error at all, it's actually not uncommon in programming languages to do that, it even has a fancy name I can't remember. I'm not sure what advantages there are to it, but C (scanf) and C++ do that. ----------------------------------- Cyril Tue Feb 23, 2010 10:06 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Don Mills CI: John and I got 52.

In turing if you don't put a * after a get variable statement, a space in an input will lead to the letters after the space to the next space to be the input for the next get statement. I have no idea why I didn't do it like that. For some reason I never thought of collecting the input separately, and insisted on collecting it all with one statement, then splitting it. Only took an extra line or so, but still. I'm not sure how I, and my friends that wrote it managed to miss that fact :P A friend of mine completely skipped problem three because he wasn't sure how to collect the input. ----------------------------------- jli1 Wed Feb 24, 2010 4:05 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- RAWR my s2 got 12/15 because of an error in the test data/input specs. It says in the input specs that the binary sequence will be less than or equal to 10. Test data #2 had sequences way longer than that. So mine failed it... If that statement in the specs actually means that the decimal version of the sequence is >= 10, then test data #5 and 6 fail. ... ----------------------------------- Insectoid Wed Feb 24, 2010 4:15 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- on my page it said the binary sequence would be no longer than 256. Anyway, my S1 failed on 3 test cases which consisted of 2 different scenarios I didn't realize could exist. Full marks on S2. AFTER I had written my string-splitting function in Ruby, I realized it has a command to split a string into an array on whitespace. Damn. ----------------------------------- Shanethe13 Wed Feb 24, 2010 4:39 pm Re: RE:Here we go, CCC2010 discussion zone! ----------------------------------- AFTER I had written my string-splitting function in Ruby, I realized it has a command to split a string into an array on whitespace.

It actually said 10. Its the same here: http://access.mmhs.ca/ccc/index.htm (scroll down to the pdf of the contest book). EDIT: Oh, you might have been thinking about the encoded string to be decoded. I meant the mappings for the characters. EG: Valid 2 A 011 B 111 11101111011 etc. Invalid: 2 A 000000000001 B 0000000000001 0000000000010000000000001 etc. ----------------------------------- konnetikut Wed Feb 24, 2010 5:56 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- EDIT: said something that I probably shouldn't have, yet.

The next k lines each contain a single character, followed by a space, followed by the binary sequence (of length at most 10) representing the associated code of that character.

Each question is worth a maximum of 15 points, making your total mark out of 75. Depending on how many test cases there are, you'll get X number of points for correct output on a test case.

Maybe I'll get lucky and get a point or two on it :). I don't know when my teacher will be marking it though. I hope to see some of you guys at stage 2, if I get in. And yeah, if it's like past contests, each test case is worth a different number of points. Also for test cases with multiple parts, I think you need to get them all right to get the points. ----------------------------------- konnetikut Wed Feb 24, 2010 9:38 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- so I just outputted the hard-coded number 42.

So, yea, UW asks for scores >= 45, as anything less than that is (virtually) impossible to make stage 2 with. Also, currently I know 8 people with a score >= 45. There are probably 12 other people with such a score, though I believe that a lot of people got stuck at #3 or even #4 and didn't even reach #5. So, yea, the cutoff could be 45, or even (a small possibility) less than 45. ----------------------------------- bbi5291 Fri Feb 26, 2010 7:31 pm Re: RE:Here we go, CCC2010 discussion zone! ----------------------------------- No. Last year's cutoff, I believe it was 49, was the lowest cutoff for any CCC.

Ok, its the third time in a row something stupid like this happened.

Oh well, I guess if something stupid happens to you three times in a row (Gr 10 - Forgot to save #4, Gr 11 - Teacher didn't mark my #2, and now Gr 12 - Didn't submit #3), then I probably am not meant for Computer Science.... Hmm...maybe if I switch into something else... To think I got into universities for CS/Math.... ----------------------------------- SNIPERDUDE Tue Mar 02, 2010 9:03 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Don't worry about it - I'm detail oriented with the memory of a gold fish. ----------------------------------- That Asian Guy Fri Mar 05, 2010 4:15 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- i got 51 on the junior think its enough to make the ranking in their results file they post every year? :P ----------------------------------- Cyril Sat Apr 03, 2010 11:16 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- 4/04 CCC results not found... ----------------------------------- bbi5291 Sun Apr 04, 2010 11:21 am Re: RE:Here we go, CCC2010 discussion zone! ----------------------------------- 4/04 CCC results not found...

I have a few things to say to invitees who are lurking here (I know you're there). My school's concert is during that week, so I'll bring my alto sax to practice with. If you play an instrument, please bring it, so we can play together. I can also offer to bring a (piano) keyboard. Those who were there last year might remember my affliction for food. If I had poisoned my beef jerky, Brian would have been knocked out cold! I will probably bring enough to feed a small country- or, equivalently, two dozen programmers. Last time, I emphasized that we needed more Gamecube controllers. Will bring. If you're a cuber, bring cubes. And don't practice pool at all, so we all look equally ridiculous. Good luck to all, and let's have fun! ----------------------------------- bbi5291 Mon Apr 05, 2010 10:00 am Re: Here we go, CCC2010 discussion zone! ----------------------------------- 41... lowest cutoff in CCC history. Congrats to Jacob, who was first in Canada with a score of 72. Assuming stage 2 is out of 600, he's 48 points --- half a problem --- ahead of everyone else (the next highest score is 60). Also, it looks like there is actually a girl invited this year... wow. ----------------------------------- McKenzie Mon Apr 05, 2010 1:07 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Interesting. There are six schools sending more than one candidate. Last year there were only three and I think that is more typical. If there is only one student at the school it may or may not be a strong program but when there is more than one odds are it's something that is happening at the school that fosters excellence. ----------------------------------- andrewshen123 Mon Apr 05, 2010 2:36 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- Does anyone know how the week 1 AP tests are supposed to fit in with stage 2? ----------------------------------- bbi5291 Mon Apr 05, 2010 3:42 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- According to Ali (who missed stage 2 due to IB exams last year), Troy will let you write stage 2 from your school if it is really necessary. Obviously the best thing to do at this point is to contact Troy as soon as possible. ----------------------------------- konnetikut Tue Apr 06, 2010 8:17 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- opt to take Form B for AP exam conflicts. http://professionals.collegeboard.com/testing/ap/coordinate/late You might have to pay a $40 fee /exam.. also, Chris Robart of MMHS has posted his solutions, and is looking for a working S5 answer, in case if anybody hadn't noticed already. http://access.mmhs.ca/ccc/ ----------------------------------- bbi5291 Tue Apr 06, 2010 9:19 pm Re: Here we go, CCC2010 discussion zone! ----------------------------------- I'll code it up tomorrow if I'm not too lazy... my original solution only memoized vertices (not edges), so it was excessively slow and not suitable for demonstration ----------------------------------- That Asian Guy Wed Apr 07, 2010 3:23 pm RE:Here we go, CCC2010 discussion zone! ----------------------------------- yes!! 51 got me a group 3 ranking im in grade 12 but i did the junior so i could be mentioned :P i guess thats reasonable considering i didnt take ics 4u1
