Do you mean to ask if everyone gets the same problems regardless of experience, and skill level?
If so, yes, everyone gets the same problems.

We're bringing back #CJTBT to help new and existing members of #CodeJam2015 prepare for this year's contest, which is kicking off on April 10th. Today's problem, "Deceitful War," comes from last year's qual round and was difficult to understand but easier to solve. See how you do! http://goo.gl/CvpJWB 
We're now waiting for the contest to start. Once the contest starts, the problems will automatically load, and Problem A will display here. You don't have to solve that problem first; you will be able to select another problem from the list to the left. Once you've solved one problem, ...

She could have used an initializer list, or a paper one; -would have been more helpful for the both of them.

About this community

Since 2003, Google Code Jam has brought together professional and student programmers from around the world to solve tough algorithmic puzzles. Competitors may use any programming language and development environment to obtain their solutions. The competition begins with three online rounds consisting of a set of a mix of algorithmic problems which must be solved in a fixed amount of time. Each year, the top top twenty-five competitors from the online rounds compete in the Code Jam Finals at a Google office; they aspire to walk away with the coveted Code Jam Champion title and a cash prize.

I want everyone to share your knowledge about #distributed-programming and skills. How to write programs in familiar programming languages(such as C++, Java , Php , Python etc  ) for distributed computations. If possible share some sample source codes...

Well, if you're working in Python, you need to keep the GIL happy.  Basically, multithreading for processing doesn't work very well because the GIL only executes one thread at a time.  (Although multithreading for I/O bound operations or NumPy stuff works fine).  Hence multiprocessing, with its higher overhead and separate memory is usually required.  But hey, you don't have to keep track of mutexes that way!

Need a bit of inspiration while preparing for the Qualification Round that kicks off on April 10th? Check out the amazing coding skills of last year's winner, Gennady.Korotkevich, at the #CodeJam2014  World Finals: http://goo.gl/IYcTsN #CodeJam2015

Hi..I am new to Code Jam..I have solved the given practice problems in Java..The solution matches with the given input..But I am not understanding the meaning of small and large inputs..

Small input means your code is good for most of the possible scenarious but large input tries to test it in every possible scenario. So if it passes small then your code is good but if it goes also with large is excellent. The real difference is that large gives you more points, if you are totally sure your code is right then it must pass large

Usually people don't directly input it manually, they manually pipe the input file into the Python script as stdin.  If you want to directly manage file input/output in Python, take a look at my template code for the GCJ: https://caethan.wordpress.com/2013/04/27/gcj-template-code/
