Data Structures and Algorithms (DSA) Theory

Data Structures and Algorithms (DSA) are the building blocks of computer science. Understanding DSA is crucial for any programmer looking to develop efficient and scalable software solutions.

Basic Concepts

• Data Structures: These are a way of organizing and storing data so that it can be accessed and modified efficiently. Common data structures include arrays, linked lists, stacks, queues, trees, and graphs.

• Algorithms: These are step-by-step procedures to solve a problem or perform a computation.

Key Data Structures

• Arrays: A collection of elements, each identified by an array index or key.
• Linked Lists: A sequence of data elements, each pointing to the next element.
• Stacks: A linear data structure that follows the Last In First Out (LIFO) principle.
• Queues: A linear data structure that follows the First In First Out (FIFO) principle.

Key Algorithms

• Sorting Algorithms: Algorithms that put elements of a list in a certain order. Examples include Bubble Sort, Merge Sort, Quick Sort, etc.
• Searching Algorithms: Algorithms that find the position of an element in a list. Examples include Linear Search, Binary Search, etc.
