----------------------------------- Reality Check Tue Feb 27, 2007 8:38 pm Today's waterloo programming contest... ----------------------------------- How did you guys find it? I think I just experienced the WORST day of my life. I did the junior one and I finished 4 for sure. I tested them and ran them and it was all good. I got to the last one with about 30 minutes left. So I was rushing the 5th. I don't remember but I think I actually had it down with like 2 minutes left to go and then when I ran it, it said: "The environment has crashed not your program bla bla bla bla" THAT PISSED ME OFF!! I think I almost cried. I finally understand the meaning of FREQUENTLY save your program...rather than save it at the end. How did the rest of you guys do? I know the best in our school finished 3 in the senior. I elected not to do the senior but after looking at the programs, I probably could have done 2 at least and MAYBE the third. What is a good mark for the junior? I'm really disappointed I didn't finish but oh well. I know 3 is pretty good for the senior but I'm not sure about junior... ----------------------------------- klopyrev Tue Feb 27, 2007 8:41 pm Re: Today's waterloo programming contest... ----------------------------------- What school are you from? KL ----------------------------------- Reality Check Tue Feb 27, 2007 8:45 pm Re: Today's waterloo programming contest... ----------------------------------- Langstaff SS. How much did you finish? ----------------------------------- klopyrev Tue Feb 27, 2007 8:59 pm Re: Today's waterloo programming contest... ----------------------------------- I finished all 5 in the senior with 5 minutes to spare :P KL ----------------------------------- Reality Check Tue Feb 27, 2007 9:06 pm Re: Today's waterloo programming contest... ----------------------------------- ^^^Wow. I was under the impression that its impossible to finish all 5... ----------------------------------- PaulButler Tue Feb 27, 2007 9:36 pm RE:Today\'s waterloo programming contest... ----------------------------------- Not only that, klopyrev had nice, fast code :). I finished them all as well but I will loose points for speed I'm sure. ----------------------------------- klopyrev Tue Feb 27, 2007 9:41 pm Re: Today's waterloo programming contest... ----------------------------------- Unfortunately, the solution I have posted is not the same I had on the contest. The one I had on the contest will work in time for most cases, except maybe for when N = 30000 and W = 2 - 50. The solution for 4 is the same, though. KL ----------------------------------- haskell Tue Feb 27, 2007 9:50 pm RE:Today\'s waterloo programming contest... ----------------------------------- What language are these conducted in? Turing? Pascal? Java? ----------------------------------- PaulButler Tue Feb 27, 2007 9:54 pm RE:Today\'s waterloo programming contest... ----------------------------------- Stage one of the test is conducted in pretty much any language your school will allow... Java/C++/Turing seem to be the most common. Stage two is C++ and Pascal only, maybe one other. I read somewhere they might add Java to the list this year but I'm not sure if this is the case. ----------------------------------- klopyrev Tue Feb 27, 2007 9:57 pm Re: Today's waterloo programming contest... ----------------------------------- Stage 1 is any language supported by the school. Stage 2 is C/C++ and Pascal. Since I am only familiar with Java, I am starting to learn C++. Hopefully I will be ready in time for stage 2. KL ----------------------------------- klopyrev Tue Feb 27, 2007 10:00 pm Re: Today's waterloo programming contest... ----------------------------------- Wow, this forum seems to be rather popular today. Wonder why... Did something big happen today that I am not aware of? End of the World? KL ----------------------------------- Clayton Tue Feb 27, 2007 10:21 pm Re: Today's waterloo programming contest... ----------------------------------- CCC happened today ;) ----------------------------------- Reality Check Wed Feb 28, 2007 12:36 am Re: Today's waterloo programming contest... ----------------------------------- So klopyrev is pretty much a programming genius then? My teacher told me the highest mark ever was a 73/75. Simply finishing all 5 is amazing in itself. ----------------------------------- klopyrev Wed Feb 28, 2007 12:50 am Re: Today's waterloo programming contest... ----------------------------------- Programming Genius? Wouldn't call myself that. I just spend a lot of time practising. I am not as good as that guy bugzpodder was taking about who finished this whole contest in 1 hour. I would like to be that good, though. KL ----------------------------------- wtd Wed Feb 28, 2007 1:42 am RE:Today\'s waterloo programming contest... ----------------------------------- C++, Pascal Turing and Java? Maybe if they let you guys code these things up in a concise language you wouldn't be pressed for time. :) ----------------------------------- zylum Wed Feb 28, 2007 2:12 am RE:Today\'s waterloo programming contest... ----------------------------------- wtd, the time spent coding a problem isn't so much an issue as coming up with a good algorithm. ----------------------------------- wtd Wed Feb 28, 2007 2:51 am RE:Today\'s waterloo programming contest... ----------------------------------- Yeah, but having to write out boilerplate doesn't help. ----------------------------------- Naveg Wed Feb 28, 2007 8:34 am RE:Today\'s waterloo programming contest... ----------------------------------- Actually, using Java for these helps immensely because of the standard library. For example, on S1 you could have just made two date objects and compared them. No more than 5 lines of code. ----------------------------------- klopyrev Wed Feb 28, 2007 11:21 am Re: Today's waterloo programming contest... ----------------------------------- I really like TopCoder's contests. Unlike all the other contests, you don't have to spend any time reading the input from the file and such, which saves a significant amount of time if the problem is easy. That allows contestants to be able to finish the easiest problems in a minute or two. KL ----------------------------------- Reality Check Wed Feb 28, 2007 4:27 pm Re: Today's waterloo programming contest... ----------------------------------- Oh man I feel so ashamed of myself. I got a 45/75 in the JUNIOR!! Thats sad. My first 3 programs worked perfectly and then the 4th messed up thanks to that dammed environment crash! Anything less than a 60 in junior is complete failure to me. In spite of this, I vow to myself that this summer I will do nothing but code. Go ahead, call me a nerd but I'll do it. I will practice practice practice. I'll do all of the previous problems and complete as many online problems I can find. I'm shooting for a 60/75 in the senior next year. Anyone have any suggestions for me? Any exercises I can do over the summer to better myself? lol whats even funnier is that last night I had a horrible dream. I was playing hockey with friends and out of thin air a popup comes and gives me the same message the environment gave me during the contest. ----------------------------------- klopyrev Wed Feb 28, 2007 9:45 pm Re: Today's waterloo programming contest... ----------------------------------- I'm soo happy!!! I just found out that I got 69 on the senior!!! :P These 2 tedious months of non-stop practise paid off!!! Go USACO!!! Going to stage 2 I think.

Do you have the breakdown of the values of each question? I hope I find out my score soon. Edit: I found the test data online, if anyone is interested: [url=http://access.mmhs.ca/ccc/index.htm#2007%20Problems]http://access.mmhs.ca/ccc/index.htm#2007%20Problems ----------------------------------- Reality Check Wed Feb 28, 2007 11:08 pm Re: Today's waterloo programming contest... ----------------------------------- Ahh so the secret is tedious months of practice. I shall do that in the summer and the months leading up to the contest. ----------------------------------- klopyrev Thu Mar 01, 2007 1:23 am Re: Today's waterloo programming contest... ----------------------------------- Hmm... Bad usage of the word tedious. Those months of practise were actually quite enjoyable :P KL ----------------------------------- Reality Check Thu Mar 01, 2007 10:59 am Re: Today's waterloo programming contest... ----------------------------------- that was a given. Programming in general is interesting and enjoyable for me and you shouldn't be doing it if isn't. ----------------------------------- neufelni Thu Mar 01, 2007 11:17 am Re: Today's waterloo programming contest... ----------------------------------- Oh man I feel so ashamed of myself.

If you want some good problems to practice, check out [url=www.projecteuler.net]Project Euler. Some of them are quite challenging, but they're fun. ----------------------------------- bugzpodder Thu Mar 01, 2007 11:34 am RE:Today\'s waterloo programming contest... ----------------------------------- project euler wont help with CCC ----------------------------------- klopyrev Thu Mar 01, 2007 11:41 am Re: Today's waterloo programming contest... ----------------------------------- They're still quite fun and really addicting. KL ----------------------------------- cool dude Thu Mar 01, 2007 4:59 pm Re: RE:Today\'s waterloo programming contest... ----------------------------------- project euler wont help with CCC what will help and is a highschool level? ----------------------------------- PaulButler Thu Mar 01, 2007 5:05 pm Re: RE:Today\'s waterloo programming contest... ----------------------------------- project euler wont help with CCC Although they are mostly different topics, I did learn dynamic programming from project euler which I could have used on S4. Personally I think any kind of exposure to different problems will help with CCC. cool dude, try TopCoder's high school questions. TopCoder.com. ----------------------------------- neufelni Thu Mar 01, 2007 6:27 pm Re: Today's waterloo programming contest... ----------------------------------- Well, I've never done CCC, so I don't know what the problems are like. ----------------------------------- klopyrev Thu Mar 01, 2007 7:48 pm Re: Today's waterloo programming contest... ----------------------------------- The best training I know of is USACO Training. ace.delos.com/usacogate KL ----------------------------------- Naveg Thu Mar 01, 2007 8:11 pm RE:Today\'s waterloo programming contest... ----------------------------------- USACO is pretty tough... I'm finding it be anyways. The actual lessons are very short, and the problems are fairly difficult. Can anyone recommend a good site that has more educational material on similar topics? Right now I'm stuck on milk2...it works for everything up to test case 7. ----------------------------------- klopyrev Thu Mar 01, 2007 11:56 pm Re: Today's waterloo programming contest... ----------------------------------- You can find very good lessons on TopCoder.com, Educational Content. They are very good and detailed but there are very few of them. I can also recommend several books. The best one I know of is CLRS (Introduction to Algorithms). Another good one is Programming Challenges. If you want any of them, I have a link to the website containing CLRS in HTML form and the other in PDF format. Contact me if you want them. KL ----------------------------------- zylum Fri Mar 02, 2007 12:29 am RE:Today\'s waterloo programming contest... ----------------------------------- not only is the educational content great on topcoder but the write ups for each problem set help a great deal.
