coursera data structures

What is a data structure :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 othertypically, a well-chosen data structure can lead to higher operational or storage Efficiency.

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

Special statement: This article refers to the blog: http://blog.csdn.net/wolenski/article/details/7951961#comments Heap and stack in my eyes has been a very vague concept, but simply understood as: the stack is a data structure, is used to store data. Because some of the things that have been studied recently, there are more heaps and stacks involved, has always been in a vague state, so after careful stud

The programThe purpose of this assignment are to provide some exercise in using multiply-linked data structures. Your program would be a number Grid . It would provide a grid with ten rows and six columns. a cell in the grid can hold and display either a number (a double) or a string. Operations is provided which display the grid, assign values to the cells, does arithmetic on cells, does arithmetic on R

The latest version of this article has been updated to: http://thinkinside.tk/2013/05/09/r_notes_2_data_structure.html Although R is object-oriented, I personally think that the so-called objects in R are only a structure (struct ). You still need to use the function to operate it. The data structure in R is mainly oriented to some concepts in linear algebra, such as vectors and matrices. It is worth noting that there is actually no simple

in computer buckets. Common storage structures include storage structures such as order, link, and index.4. graphical representation of the data structure:In the data structure, a node without a front component is called a root node; a node without a back component becomes a terminal node. Insert and delete are two ba

Two special data structures: queue and stack; two types of data structure queue I. Queue Queue (Queue: the first data structure to be introduced in this article): You can only add (offer) elements from one end of a linear table and retrieve (poll) elements from the other end, and follow FIFO (first-in-first-out) Select
