The Google Code Jam is coming to China! This is your chance to compete against your countrymen and women in the search for China's finest.
We've got tough problems, hi-tech prizes and bragging rights up for grabs. Think you have what it takes?
This is how it works
The tournament is a timed contest where all participants compete online to solve the same problems under the same time constraints.
The competition is available in four programming languages - Java, C++, C#, and VB.
A wizard with C but rusty with C++? Don't worry! We've got it covered. Check out the C++ for C Programmers page that shows you the basics of learning C++ for the competition. Also, be sure to spend time in the Practice Rooms by clicking on the Competition Arena link above.
Here's the line-by-line documentation:
Download the Arena
The TopCoder® Competition Arena (a Java Applet) is where you begin. Download the app, read the problem statements, then code solutions, compile and test those solutions and submit the code for points. You can download the arena ahead of time to practice on sample problems prior to the competition.
Coding Phase
At the designated date and time, competitors enter the Arena and are placed in groups of ten into virtual rooms. All participants are presented with the same set of three problems of escalating difficulty. In a race to see who can create an accurate solution in the shortest amount of time, competitors try to out-think and out-code their opponents. The Leader Board tallies the points during each step of the competition.
Challenge Phase
During the Challenge Phase, competitors view each other's code and try to "break'" that code by passing test cases through the submitted code, with the hope that the results are not satisfied by the software written. Breaking another developer's code is the most direct form of competition for a programmer. In this phase, points are awarded for successful challenges and deducted for unsuccessful challenges.
System Tests
Within minutes of the end of the Challenge Phase, the automated, objective system tests determine the accuracy of all submissions and award final points to all competitors. The assessment of your performance and presentation of stats is nearly instantaneous, as is the gratification of knowing how you did against a competitive field.
