1, LinkedList composed of one and one Node: [data][next]. [head] -> [data][next] -> [data][next] -> [data][next] -> [null]. Empty linkedList: head == null. V.S. Array DS: fast at insert/delete. 2, hashtable “数组可以通过下标直接定位到相应的空间”,对就是这句,哈希表的做法其实很…
Arrayss work well for unordered sequences, and even for ordered squences if they don't change much. But if you want to maintain an ordered list that allows quick insertions and deletions, you should use a linked data structure. so inserting an elemen…
"I worked up a full implementation as well but I decided that it was too complicated to post in the blog. What I was really trying to get across was that immutable data structures were possible and not that hard; a full-on finger tree implementation…
原文链接:http://www.codeproject.com/Articles/9680/Persistent-Data-Structures Introduction When you hear the word persistence in programming, most often, you think of an application saving its data to some type of storage, such as a database, so that the…

What is a high-performance data structure? To answer that question, we're used to applying normal considerations like Big-Oh complexity, and memory overhead, locality, and traversal order. All of those apply to both sequential and concurrent software…
10.2 How would you design the data structures for a very large social network like Facebook or Linkedln? Describe how you would design an algorithm to show the connection, or path, between two people (e.g., Me -> Bob -> Susan -> Jason -> You).…
