The Programming Contests, Challenges and Online Judge Thread.

[QwertyManiac]

You can do several of the mentioned in Java, can you not?

 

[Sykora]

All of them, except CodeGolf and Pythonchallenge.

 

[QwertyManiac]

Can someone post a simple example of how an SPOJ submission should take input as.

Is it via STDIN or via a file? A sample solution that reads one test case amount line, and a test case is enough. Python preferrably.

great great sites... just the thing I was looking for

 

[::cyborg::]

thanks for the links nice thread

 

[Sykora]

@Qwerty :

I think it is mentioned on all problems that input is taken from stdin. However, it is obvious that the input is redirected from a file, and stdout is redirected to a file.

The general construct is this :

numTestCases = int(input())
for i in range(numTestCases) :
    # Do stuff here
    #
    #

    print(result)

No, I don't store the results and print them out later, because it doesn't make a difference to the judge, and you gain time _and_ space.

 

[QwertyManiac]

Thank you for clearing it up! I had got confused about it actually. And thanks for the efficiency tip too.

Btw, doesn't input() automatically convert to int on passing an input w/o quotes?

 

[Sykora]

^^^ I've gotten used to python3.0 where raw_input() became input, and input was removed in favor of eval(input).

 

[QwertyManiac]

Oh ok, that's a nice change.

I vote this thread sticky.

Edit: And it is! w00t!

Current Contests (To be held today, the 9th of March):

1. Anna University's CodeArena @ SPOJ.pl (Contest Ended at 18:00 Hours)
--------------Allowed Languages: Many (C/C++, Java, Ruby and Python inclusive.)

2. IIITM Gwalior's Code Weavers (Contest Ended at 1800 Hours)
--------------Allowed Languages: Restricted (C/C++, Java)

Both events have team participation as well, so good luck all!

Another good problem resource (Eternal):

IIT-K's Bitwise Annual Algorithm Challenge
(Its over for this year already, but problems remain, from every Bitwise there ever was. Very good problems!)

Did Harsh or Sykora partiticipate? Anyone else did?

 

[QwertyManiac]

Yep we did, the CodeArena one. Not sure if anyone else from here did too.

 

[Sykora]

The SPOJ Open Contest 2008 is now running, from May 3 to 20.

You can find it at *www.spoj.pl/ZFUN08/ .

 

[QwertyManiac]

I did the BCH problem there, got a chain of 968 numbers / 1061 maximum Will try that one again in this week to max out.

 

[aditya.shevade]

^^ Good for you... it looks like you can participate more than once in the same contest.... :-/

 

[mehulved]

Registrations have begun for Google Code JAM - *code.google.com/codejam/

 

[Sykora]

They've changed the format a lot since last year -- thank goodness for that.

You're participating? I believe harsh is.

 

[QwertyManiac]

How would Sykora _not_ participate?

I haven't the time though, I'll try weekends.

 

[aditya.shevade]

hehe... no one will give you answers... you can ask for hints... but not answers directly... and PLEASE do not post answers.
