登陆进去之后,发现题目都看不太懂,我的英文啊.

There is a practice room available to you that will allow you to become acclimated with the competition environment before you participate in the Google Code Jam 2005.  The practice room contains a problem set that will be very similar in nature to the problems you will encounter during competition.  The practice room will be available from 9:00AM EDT on July 25, 2005 through 5:00PM EDT on September 23, 2005.

You can access the practice rooms by navigating to http://www.topcoder.com/googlecodejam and clicking on the Competition Arena tab.
