All the code in this article is big root heap! The implementation language is Java The pictures are all from the great God, and the great God's articles also give me a lot of inspiration Heap of data structures Heap sort This video is easy to understand, from what is heap, what is heap, and then to the realization of heap sorting. It is ver ...

0. Learning objectives Python is a concise, easy to learn, object-oriented programming language. It not only has powerful native data types, but also provides simple and easy-to-use control statements. stay Python based variables and built-in data types In, we introduced the built-in native data types in Python. The main goal of this ...

Redis has five basic data structures: 1. String (string) 2. List 3. Hash (Dictionary) 4. Set 5. Zset (ordered set) There are eight categories of data structures: 1. Array 2. Stack 3. Queue 4. Linked list 5. Tree 6. Hash table 7. Pile 8. Figure Java has eight basic data types (it doesn't matter, but by the way 😜)， They are: 1. Byte (bit) 2. ...

[preface] in the previous article, we have learned about the basic functions of sequential list and single linked list. Next, let's learn how to realize the basic functions of two-way linked list. First, let's take a look at the structure of the two-way linked list: Headless bidirectional linked list Concept and structure of bidirectio ...

1, List frame construction 1. Introduction list is a sequential container that can be inserted and deleted at any position within the constant range, and the container can iterate back and forth.The bottom layer of list is the leading two-way linked list structure. Each element in the two-way linked list is stored in independent nodes t ...

Deep development post, in fact, sorting is also an inseparable link. Bubble sorting, selection sorting, insertion sorting, merge sorting, quick sorting and heap sorting are also the technical points I have frequently asked since the autumn move Sorting algorithm has two important knowledge points Memory consumption: the memory consumption o ...

This paper summarizes some basic operations of chained binary tree in class, including Calculate the number of nodes of the binary treeCalculate the number of leaf nodes of binary treeCalculate the number of nodes in the K-th layer of the binary treeCalculate the depth / height of the binary treeFind and return the node with the value of x ...

1, Concept and application of construction method Constructor is a special method in. Its name must be exactly the same as that of its class, and there is no return value, and there is no need to use the keyword void for identification. For example: public class Apple{ public Apple(){//Default construction method } } 1. Default constru ...
