A data structure is a set of data values and the relationships that exist between them. Data structures enable programs to store and process data effectively. There are numerous data structures, each with its own set of benefits and drawbacks. Arrays, lists, trees, and graphs are the most common data structures.
What exactly is a Data Structure?
Data Structure, as the name implies, organizes data in memory. Numerous methods for organizing data in memory include arrays, lists, stacks, queues, and many others.
The data structure is not a programming language such as C, C++, Java, etc. It is a set of algorithms that can organize data in memory in any programming language. Take a look at this instructor-led data structure and algorithms course right now!
Data Structure Is Required
As applications become more complex and the amount of data increases, this may cause issues with processing speed, data searching, handling multiple requests, etc. The data items can be easily traversed with the help of data structure. It is crucial in improving a program’s performance because its primary function is to store and retrieve the user’s data as quickly as possible.
Why should you learn data structure?
Two of the essential aspects of computer science are data structure and algorithms. Data structures enable us to organize and store data, whereas algorithms allow us to process that data meaningfully. You will become a better developer if you learn data structures and algorithms. You will be able to write more efficient and reliable code. You’ll also be able to solve problems faster and more effectively.
Data Structure Types
There are two types of data structures:
Primitive Data Structure
Non–Primitive Data Structure
Primitive Data Structure
Primitive Data Structures operate directly on machine instructions. These are the basic data types. Integer, char, float, double, and pointer data types are primitive data structures that can only hold one value.
Non–Primitive Data Structure
Non-primitive data structures are those that are more complex than primitive data structures. Non-primitive data types are further classified into two types.
Linear Data Structure
Non – Linear Data Structure
Linear Data Structure
A linear data structure is made up of data elements arranged in sequential order, with each element connected to the elements before and after it. This connection allows you to traverse a linear arrangement in a single level and run. Because memory is also sequential, such data structures are simple to implement. List, Queue, Stack, and Array are examples of linear data structures.
Non-Linear Data Structure
Non-linear Data Structures have no fixed sequence for connecting all their elements, and each element can have multiple paths to connect to other factors. Such data structures can support multi-level storage and are not always traversable in a single run. Such data structures are difficult to implement but are more memory efficient. Tree, BST, Graphs, and other non-linear data structures are examples.
Data Structure Classification
Data Structures are further classified as follows:
Static Data Structure
Static data structures are those whose size is determined at compile time. As a result, the maximum size is fixed and cannot be altered.
Dynamic Data Structure
Dynamic data structures are data structures whose size is determined at run time. As a result, the maximum size is adaptable and can be changed as needed.
Data Structure Benefits
Data structures allow for storing information on hard discs.
Choosing an appropriate ADT (Abstract Data Type) makes the program more efficient.
Data structures are required for the development of efficient algorithms.
It allows for reuse and abstraction.
Using appropriate data structures can help programmers save time when performing data storage, retrieval, or processing operations.
Large amounts of data are easier to manipulate
