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

For other Java persistence solutions, it is very easy to integrate hibernate into a Java application.Compared with other solutions, Hibernate designers avoid more common defects and problems and create a lightweight but powerful framework.Lightweight, that is, we do not need a specific J2EE

07. C # Brief description of generic restrictions and empty types (Chapter 3, chapter 2-Chapter 4, Chapter 3.5 ), While writing articles, I am also learning. I don't have a good understanding of many statements in the book. Read a book and digest it !!! The three chapters are about generics. Finally, let's write the limitations on generics. for the end of this chapter, one end, one begin. See the following

Layer-2, layer-3, and layer-4 switches have different characteristics. layer-2 switching is a mature technology. A layer-2 switch is a data link layer device that can identify MAC address information in data packets, forward based on the MAC address, and record these MAC addresses and corresponding ports in an internal

2-3-4 is a type of B tree with a level of 4. It is a self-balancing data structure that can be searched, inserted, and deleted in O (lgn) time. Here N is the number of elements in the tree. 2-3-4 trees are equivalent to the red-black tree, that is, each red-black tree can be

Xception: Here we have a picture of a Scottish barrel, especially my favorite Scotch whisky, Lagavulin. Xception correctly classifies this image as "buckets".The last example is to classify using VGG16: A few months ago, when I finished the game of the Wild Hunt, I took this photo of the monitor. VGG16 's first prediction was "home theater", which was a reasonable prediction because there was a "TV/monitor" in the top-5 forecast.As you can see from the examples in this article, the
