Today I attended the Amozon Online Test, very unlucky. First I couldn't start the test with firefox, it wasted about 5 minutes. Then when I solved the parenthesis balanced problem, I implemented a wrong algorithm which waste about 30 minutes.  The "root cause" is that I wasn't familiar with these problems, I mean I should have practiced these problems usually, otherwise it's impossible to solve these problems in a test immediately. Another "root cause" is that I want to use some tricky methods in test, it wasted time too. Next time I will use a normal and clear algorithm in test. There's no enough time in a test for me to optimize a high performance version, I should implement feature first.

These days the most important feature of computer is to save and process data, so data structure and algorithm is the core of computer. I should enhance my data structure and algorithm knowledge. I create a plan for this purpose:
1. review algorithm and data structure everyday; ( Attention: 1 hour for English, 1 hour for algorithm )
including the book coding interview, this amozon test such as the list merge problem, challenge test on uva and https://www.hackerrank.com/, design patterns, the implementation of important algorithm or data structure such as AVL.
2. write and rewrite my blog in english, describe my project experience in english, review english vocabulary。
