[gcj] Re: Query

[Bartholomew Furrow]

We'll have to ask for your patience here -- we're working our way through a
large number of cheating claims.  Plus it's a weekend, so a lot of the team
is recovering from a very hectic week. :-)  Rest assured that if you have 33
points (and didn't cheat, of course), you qualified.

Regards,
Bartholomew

 Hi,

 I understand that this query has been raised time and again, even I have
 asked before.
 But it is 7th today and its been 5 days since the contest, and I haven't
 seen any change on the main site indicating my qualification or otherwise.

 My rank is shown as 6000 with a score of 33 and a lot of people have
 told me that this should imply that I have qualified, but I am surprised as
 to why is there no indication on the codejam main site.

What a huge list.

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.

is a signed number that identifies an object and is defined in Object

The java documentation gives the contract that you must follow if you

[Xiongqi ZHANG]

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 > output.out

after your program finished, output.out will contains everything you print to 
stdout. Everything you print to stderr should still go to the console.

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.

Re: [gcj] Re: query

[Paul Smith]

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 objects cannot be sorted as they don't
really have an ordering, and some objects are huge so looking them up
is really inefficient that way.

What you need is some way to quickly convert any object into a
integer, like some kind of identity code, you can then store objects
based on that code, and lookups become much much faster.

That's the hashcode.

It doesn't save your complete headache - 2 objects with the same
hashcode aren't necessarily equal, so once you've found all the
objects with the hashcode that you're looking for, you still have to
check the real object for equality - but hash collisions are rare.  At
least, with a good hashing algorithm they are ;)

hey dear,
you have to solve 1 out of 3 questions for qualifying round.if u have

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.

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.
But if i know that i did right in small input for Q1 and m sure all of the
other two questions are wrong for small input, and if im sure that i did
right in large input for Q3 theni can be relaxed. Basically just wanna know
"*if smal and large of same question should be correct in order to advance
to round 1 or 1 small of any thrree questions and 1 large of any three

Any small, and any large.  (It would be unusual to have the large correct

[gcj] Re: query on qualification round

[Ziv W]

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 clear. In this case, I think the point is that it's not
enough to rack up easy points by writing naive solutions to all of the
small inputs - you've got to complete at least one of the big ones.

Good luck! :)

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.

[David M.]

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...

[gcj] Re: query on qualification round

[Himanshu Sachdeva]

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 nice.


Cheers!

[Himanshu Sachdeva]

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 result for large input untill the round is over.

Cheers!

Yes, but you do know if it is wrong for the small, and if it is wrong for
the small then you can be almost positive the large is wrong as well.

[gcj] Re: query regarding opening input files in java

[SkidanovAlex]

In order to read from file

BufferedReader bf = new BufferedReader( new FileReader
( "problem.in" ) );

Than you can read one line of input by calling:

String s = bf.readLine( );

If string has some tokens, separated by space (for example two
integers) use StringTokenizer class. For example if you want to read
two integers:

StringTokenizer st = new StringTokenizer( s );
int n = Integer.parseInt( st.nextToken( ) );
int m = Integer.parseInt( st.nextToken( ) );


Writing:

PrintWriter pw = new PrintWriter( "problem.out" );
pw.println( "Omg! It works!" );


One more peace of advice. Never use more than one question mark in a
row :o)

Also some java coders like using Scanner class
It is a bit easier than BufferedReader/StringTokenizer, but it is
slower as well
