数据结构三大块

一维数据结构

基础：数组array(string),链表linked list
高级：栈stack,队列queue,双端队列deque,集合set,映射map (hash or map),etc

二维数据结构

基础：树tree,图graph
高级：二叉搜索树binary search tree (red-black tree,AVL),堆 heap,并查集disjoint set, 字典树Trie,etc

特殊数据结构

位运算Bitwise,布隆过滤器BloomFitter
LRU Cache

算法八大点：

基石三大点：

If-else,switch --->brach
for, while loop -->Iteration
递归Recursion (Divide & Conquer,Backtrace)

五大高级点：

搜索Search：深度优先搜索Depth first search,广度优先搜索Breadth first search，A*，etc
动态规划Dynamic Programming
二分查找Binary Search
贪心Greedy
数学Math，几何Geometry

算法经典友好书籍

《算法红宝书第四版》

对每一个算法知识点讲得都很详细，同时不是很繁琐，比较容易上手。

《图解算法》

图例很多，语言通俗易懂，学起来比较有意思。

《算法导论》

大家小学的时候肯定都有字典或工具书。
我们就可以把《算法导论》当做工具书来使用，在学完了基本的算法与数据结构，大家想对某一个知识深入学习或者复习的时候，这个时候可以查一查《算法导论》。

曾有人说，数据结构这个东西，如果你不去学，可能一辈子都感受不到它的好。但一旦掌握，就会被它的强大威力所折服。

它是底层开发的重要一环，保证底层系统的稳定性和高效性；......
从功利角度，它是大厂必考，你不可避免，从长远角度，它将决定你的技术上限。
一旦拿下了数据结构与算法，就如同站在巨人的肩膀上，在开发江湖占有一席之地。所以说难也得好好学
