1.算法
linkedlist (https://leetcode.com/tag/linked-list/)

2 pointer (https://leetcode.com/tag/two-pointers/，或是一头一尾，或是分布于
两个数据结构)

divide and conquer (https://leetcode.com/tag/divide-and-conquer/，最典型的就
是merge sort)

greedy (http://geeksquiz.com/algorithms/greedy-algorithms/，最典型的就是Schedule Activity / Job sequence / Meeting rooms)

recursion and DP (https://leetcode.com/tag/dynamic-programming/，最典型的就
是｛Longest / Maximum / Target / Largest / Minimum / Most｝ + ｛subX / 
Matrix / Tree / Path｝)

back tracking (https://leetcode.com/tag/backtracking/，真的找不到很好的方法
时，才会用它)

string (https://leetcode.com/tag/string/，leetcode还是蛮全的)

tree (最典型的就是BFS, DFS, inoder, preorder, postorder, recursive traversal
， iterative traversal, 求path，binary search tree, heap, trie，Minimum 
spanning tree，题目参看leetcode)

graph (DFS, Topological Sorting, Shortest path)

bit (https://leetcode.com/tag/bit-manipulation/)

math (https://leetcode.com/tag/math/)

2. 系统设计总结
相对算法题而言系统设计题更像送分题，当然前提是你得跟着面试官的问题走，不要不
顾面试官的想法自己横冲直撞。我这方面比较薄弱，大家可以参考版上的其他帖子。
