Welcome to the study guide on Data Structures! Whether you're a beginner or looking to enhance your knowledge, this page will provide you with a comprehensive overview of various data structures and their applications.
Basic Concepts
Data structures are a way of organizing and storing data so that they can be accessed and modified efficiently. They are crucial in programming as they help in managing data in an organized manner.
Common Data Structures
- Arrays
- Linked Lists
- Stacks
- Queues
- Trees
- Graphs
Arrays
An array is a collection of elements, each identified by an array index or key. They provide fast access to elements using their index. Learn more about arrays.
Linked Lists
A linked list is a linear collection of data elements, called nodes, each pointing to the next node by means of a pointer. Explore linked lists in detail.
Stacks
A stack is a linear data structure that follows the Last In First Out (LIFO) principle. Read more about stacks.
Queues
A queue is a linear data structure that follows the First In First Out (FIFO) principle. Learn about queues here.
Trees
A tree is a hierarchical data structure consisting of nodes. Each node has a value and zero, one, or more children. Discover more about trees.
Graphs
A graph is a collection of nodes, called vertices, and the connections between them, called edges. Explore graphs in depth.
By understanding these fundamental data structures, you will be well-equipped to tackle more complex problems in programming. Happy learning!
