About Code Jam.
Do you enjoy solving tough problems and grappling with technical challenges? Then enter Google Code Jam!
Google Code Jam is a coding competition in which professional and student programmers are asked to solve complex algorithmic challenges in a limited amount of time. The contest is all-inclusive: Google Code Jam lets you program in the coding language and development environment of your choice.
Google Code Jam begins in July and continues in August, when you will compete in online rounds against contestants from around the world. The Top 500 participants will advance to onsite competitions at a local Google office to compete against those in their region (Asia Pacific; Europe, Middle East and Africa; and the Americas). The Top 100 will participate in the final round at the Google Headquarters in Mountain View, California on Friday, November 14.
Don't be left out! Make sure to register between June 17 and July 17, and show your coding creativity in Google Code Jam.
后记：错过一步，就成了观望了。这个比赛是有严格时间控制的。必须按规定时间参加。不但要提前报名，还要在指定时间来做题。不过比赛题目不错，事后也可以做题，只是没有成绩。权当练习。
