Code and are not good at abstracting and summarizing rules. Programmers who are standing in the same place are mostly mixed meals, and they do not take the initiative to learn and improve their own consciousness.
Programmers must not only cultivate their own technologies, but also cultivate their own character. Doesn't it mean that most problems in programming are character problems? Of course, this is about the cultivation of the programmer's character and personality.

illustrates, writes an algorithm to turn the order table upside down.such as: Known order table L, write an algorithm to invert it, where (a) is inverted before, (b) is inverted.My thinking is to change the middle number of the position. The corresponding source code is as follows:public void Reversseqlist (seqlistThe algorithm simply scans the sequence of data elements in the order table once and then completes the inversion, so the time complexity
1 Overview of data structures
A data structure is an arrangement that refers to a computer's memory (or disk).

Time Test
This book uses a practical method to analyze the data structures and algorithms to be studied. We prefer to use a simple benchmarking method instead of Big O analysis. This test tells us how many seconds (or other time units) it takes to run a code segment. Our benchmark test time test measures the time it takes to run an algorithm. Benchmarking is a sc
To work in a computer, data must first be processed and processed by a computer. In a simple classification, data is classified into numerical data and non-numerical data. Numerical data is mainly used in engineering and scientific computing; instead of numerical
The data structure is generally and the algorithm is said together, called data structure and algorithm. This knowledge is very good to understand, but some teachers every day XXX's simply unintelligible. So I want to write this simple tutorial, the knowledge is shallow, please forgive me.

Basic Concepts
I. Data and structure
Data: All of the objects that can be entered into a computer and can be processed by a computer are collectively referred to as a specific symbolic representation of the information processed by the computer.
Data elements: An "individual" in the data, the basic unit discussed in t
What is a data structure: Statistics + relationshipsRelationships can be divided into: sets, linear structures, tree structures, graph structures or network structures.Storage structure: Sequential storage, chained storage, index storage, hash storage.Data type: Atomic type, struct type1.

Preface
"Puretalk.The goal of writing algorithms and data structures is to separate the idea of algorithms from the code details in specific implementations. We sometimes feel that once w
smaller than their own elements can stop the comparison, because the left is already an orderly state, find smaller than their own elements, there is no further comparison.
? The number of rounds to be inserted is the same as the bubbling sort, but I start with 1 because we assume that the first element is already in an orderly state.? The inner loop starts from the current position, compares it to the previous element, and if it finds a smaller element than itself, stops the comparison
, so the time complexity of the algorithm T (n) =0 (degree (v)). ⑵updatesize (): Also if the child of node v changes, the current node should be updated and the size of its ancestors. Because the scale of any node in the binary tree is equal to the size of its left and right sub-tree and the node itself, and the size of the subtree only need to get the node around the size of the child can be obtained, only the θ (1) time. Thus the algorithm's time complexity T (n) =0 (level (v)). ⑶sever (): Cut
