the problem. This is what the interviewer first wants to see. We recommend a book: Steven skiena's the Algorithm Design Manual 1) algorithm complexity analysis. you must know how to use big O to analyze algorithm complexity. if you do not know this, you will not be able to pass the interview. if you do not know, read the relevant chapter carefully. you can do it! 2) sorting algorithm. you need to k

With the huge development of the Internet, network devices are indispensable. network devices have become the cornerstone of Internet development.

improve the performance of your system by using an optimized hidden device during the query process.B + trees are most commonly used, and performance is not bad, both for range queries and single-valued queries. In particular, the scope of the query, must use the B + tree in order to be able to.Hash if only for the single-valued query speed than the B + tree faster.The use of bitmaps is very limited, only a few cases can be used, it is important to determine the real appropriate use of this ind
