说明：  本书示例丰富，图文并茂，以让人容易理解的方式阐释了算法，旨在帮助程序员在日常项目中更好地发挥算法的能量。书中的前三章将帮助你打下基础，带你学习二分查找、大O表示法、两种基本的数据结构以及递归等。余下的篇幅将主要介绍应用广泛的算法，具体内容包括：面对具体问题时的解决技巧，比如，何时采用贪婪算法或动态规划；散列表的应用；图算法；K最近邻算法。----来自百度百科
(This book is rich in examples, illustrations and texts, and explains algorithms in an easy to understand way, aiming to help programmers better play the energy of algorithms in daily projects. The first three chapters of the book will help you lay the foundation for learning binary search, big O representation, two basic data structures and recursion. The rest of the paper will mainly introduce the widely used algorithms, including: solving skills in the face of specific problems, such as when to use greedy algorithm or dynamic planning; application of hash table; graph algorithm; k nearest neighbor algorithm. ----From Baidu Encyclopedia)
