If you compare those source files you will easily realize it isn't coincidence, the solutions of many people are probably very similar, but in that list variable names, order of apparition, class and file names and stuff like that are all the same, and that is hardly a coincidence. Carlos Guía On

The best way to read input and save output to file is use I/O redirects. Basically you just read input from stdin and print the output to stdout and log your debug info to stderr. --- After you downloaded the input file and saved as input.in, you can run your program using ./myapp < input.in >

Nataraj, The hashcode method provides a hash of the object which is primarily used in hash based containers like HashSet and HashMap. I do not believe it has anything to do with memory conservation or creation of duplicate objects. Regards, Rajesh Nair On Wed, Jun 23, 2010 at 9:24 AM, nataraj s

It's all about fast lookup. Take any object, how do you look for that object in a container? Go through the container and check each object one by one until you find it? Holy O(n) lookup batman! Much better would be to sort the objects somehow and at least do binary search. However, some objec

[gcj] Re: query on qualification round

You need at least 1 small and 1 large, but if can solve more try to do it, you won't know if the large is correct until qualification ends, so it's a gamble to solve only 1 and not try the others. Carlos Guía On Wed, Sep 2, 2009 at 11:55 AM, Himanshu Sachdeva wrote: > atleast 1 small and 1 large

[gcj] Re: query on qualification round

Just notice that after you submit a large output, the site will not tell you whether it is right or not. The official result about the correctness of your large output won't be available until the qualification round ends. So, it is probably a good idea to try to solve the 3 questions just in case

YES my dear friends...i will definitely solve all three of them. Definitely.

[gcj] Re: query on qualification round

Well, I think it's assumed that if you're able to solve a large input from one of the questions, then you can solve the small one as well with exactly the same code. (Vice versa is rather less likely to be correct...) If you take a look at a round or two from last year, the concept should be clea

[gcj] Re: query on qualification round

Well, if it works on the large data set it should probably work on the small. I don't see why anyone wouldn't test on the small as if it doesn't work there it sure as heck won't work on the large. Grant Kot On Sep 2, 2009, at 2:13 PM, Anurag Dongre wrote: > YEAH i understand its a gamble

Yes and not. It can happen that a program runs ok with the small input file, but the same program fails with the large. It could had problems like an out of memory or needs a lot of time to execute... 2009/9/2 Anurag Dongre > YEAH i understand its a gamble but is it that smal and large of same >

as the rules state:"If you successfully solve one small and one large input from any of the three problems, you will advance to Online Round 1." what i get from this line is that the small and large input should be of the same problem. but if somebody from GCJ organizing team can confirm, it'll be

Grant, Ziv:the issue that was being discussed in this thread is whether you can solve small and large inputs for different problems and qualify OR you have you solve small and large for the same problem. its right that if it works for large input, it'll work for small input. but you dont know the r
