Algorithm Is used to operate data. Frequently used methods for storing information: arrays, linked lists, indirect addressing, and analog pointers, among which several arrays and linked lists are the most common. Many complex data structures are implemented based
Note: This blog is my understanding of the data structure, many local understanding may not be appropriate, but also ask the reader to learn dialecticallyUnderstanding data structures from the macro levelMany times we have been working hard, but don't know why ...After a year of work, re-think of the university's data
Stack has many practical applications. There is a decimal to binary function in the book. (If you do not know how to calculate binary, Baidu can) The following is the source code of the function.The principle is to input the number to be converted, divide it by two and take the integer. Finally, we use the while loop to splice all the numbers in the stack into strings for output.

What are the eight main construction blocks of Angular 2 applications and angular application structures?
Previous words: I recently read quickstart on the official website during Angular 2 and National Day, and wrote an article, just a hello world demo. Later, I continued to read a project tutorial of it. At the beginning, I was able to keep up with it, and it was quite confusing. Indeed, it is difficult f

Extension:Binary Trees have many extended data structures, including balanced binary trees, red/black trees, and B + trees. These binary trees are derived from many functions and are widely used in practical applications, for example, the index structure of the MySQL database uses the B + tree, and the underlying source code of hashmap uses the red/black tree.
structures are divided into logical and storage structures. Linear Linked lists are storage structures.6. The data structure includes the logical structure of the data and the storage structure of the data.7. The
1. Stack
1.1 the definition of the stack
Stacks are a kind of special linear table. The peculiarity is that the operation of inserting and deleting data elements can only be done at one end of the linear table. As shown below:
Conclusion: LIFO (last in first), abbreviated as the LIFO linear table.
The basic operation of the stack is six kinds:
Constructed empty stack: Initstack (S),
Stack empty: Stackempty (S),
Stack full: Stackfull (S),
Into the s
concept of generic programming, which can be seen as a special polymorphism. when writing a function, in order to be generic to all data types, the concept of generic is introduced to avoid paying attention to a specific type. it is like a good template. When you call it, you can upload a real type to OK. generic programming is also C #2.0 most important concepts. the most important concept in C #3.0 is LINQ. It is also used to facilitate
structuring data just as they structured control; stacks and queues as adaptations of the list structure to special applications; trees as structures that improve theoretical and empirical performance; and hash tables and priority queues as case studies in generalizing the previous ideas and applying them to new problems.
With the above tools armed, students can

? At present, the computer has been deep into all areas of social life, it is the Web front-end application, its application is no longer confined to scientific computing, and more is used in the control, management and data processing, such as non-numerical computing fields. Computer is a research computer for information representation and processing of science. This involves two questions: the representation of information, the processing of inform
The data structure is the way that the computer stores and organizes it. A data structure is a collection of elements that have one or more specific relationships to each other. Typically, a well-chosen data structure can lead to higher operational or storage efficiency. Data struc
