Data structures are a special format for organising, processing, retrieving, and storing data. Several basic and advanced types of data structures are designed to organise data for a specific purpose. The data structure makes it convenient for users to access and manipulate the data they need.

Programming and Data Structures (DS) is one of the most important subjects in computer science. This subject is weighted on average 12-15 points on GATE CS exams. Data Structures are generally a very broad topic in computer science and engineering. Different types of Data Structures are suitable for various applications, and some are highly specialised for a particular task. Data structures provide an efficient way to manage large amounts of data for applications such as large databases and internet indexing services. You can use data structures to organise the storage and retrieval of information stored in both primary and secondary storage.

There are different types of Data Structures. Some of them are mentioned below:

• Introduction to Array Notes
• Linked Lists Notes
• Binary Heaps Notes
• Heap Sort Notes
• Binary Search Trees Notes

Linked List Data Structures

Linked lists are linear collections of data elements that are not ordered by their physical placement in memory. Instead, element points are adjacent to each other. It is a data structure consisting of a collection of nodes that represent a sequence.

This is a crucial topic belonging to the famous chapter of Data Structure in Computer Science. Moreover, candidates have to read the whole topic in a detailed manner for competitive examinations like GATE. Linked lists are linear collections of data elements that are not ordered by their physical placement in memory. Instead, element points are adjacent to each other. It is a data structure consisting of a collection of nodes that represent a sequence.

Types of linked list

Some of the different types of Linked Lists are mentioned below:

• Singly Linked List
• Doubly Linked List
• Circular Linked List
• Advantages of Linked Lists

Advantages of linked lists

• A linked list is dynamic, which means it will provide memory whenever needed.
• In a linked list, we can swiftly execute the operations like insertion and deletion.
• We can quickly implement stacks and queues.
• It helps in reducing the access time.

Disadvantages of linked lists

• Sometimes the memory gets wasted because pointers need extra memory for storage.
• We can access elements in a sequence. You cannot randomly do this process.
• In a linked list, reverse traversing is challenging.

GATE CSE Preparation

To prepare for the GATE CSE examination, the candidates must study hard and gather the materials properly, as they play an essential role. We can say that perfect study material can help candidates reach a perfect preparation plan. Moreover, it will provide every detail about the GATE computer science discipline syllabus as CSE is one of the most logical and conceptual disciplines in engineering. Students who wish to appear in the GATE examination through this paper need to cover all the core technical and relevant topics.

Two things to remember:

• They can refer to the GATE notes for CSE to understand the syllabus in a better way.
• The materials they use must have detailed concepts and explanations of each topic.

Of course, there are other aspects of GATE preparation, but these are a few important tips regarding the syllabus and materials that you use.
