Recently I am studying multithreading, the title is derived from the first article of "second kill multithreading" (http://blog.csdn.net/morewindows/article/details/7392749) by Mr MoreWindows)Excerpt:
Question 5 (Google interview)
There are four threads: 1,
From the previous introduction, we know that in a binary tree, each node has only one data item, with a maximum of two child nodes. If you allow each node to have more data items and more child nodes, it is a multi-fork tree. This blog we will introduce the--2-3-4 tree, which is a multi-fork tree, with a maximum of four child nodes and three data items per node.1
Recently in the study of multi-threading, the topic originates from Mr. Morewindows's "second Kill multithreading First" (http://blog.csdn.net/morewindows/article/details/7392749)Title Excerpt:Question Fifth (Google interview questions)There are four threads of 1, 2, 3, 4.

As can be seen from the analysis of the 4th section, binary search tree is a very good data structure, can quickly find a given keyword data items, and can quickly insert and delete data items. But binary search tree has a very troublesome problem, if the tree is inserted in random data, then the performance is good, but if the insertion is ordered or reverse-order data, then the two-fork search tree execution speed becomes very slow. Because the binary tree is unbalanced when inserting values i
