This course provides a quick and practical introduction to the most important data structures used in programming and technical interviews.
The course begins with an overview of what data structures and algorithms are, explaining how they form the foundation of efficient problem-solving in computer science.
It then introduces the stack data structure, explaining the Last In, First Out (LIFO) principle and how stacks are used in real-world applications such as function calls and expression evaluation.
Next, the course covers queues, explaining the First In, First Out (FIFO) principle and how queues are used in scheduling systems, buffering, and task management.
It also introduces priority queues, where elements are processed based on priority rather than insertion order, making them useful in systems like task scheduling and shortest-path algorithms.
In addition, the course explains linked lists, showing how nodes are connected dynamically and how they differ from arrays in terms of memory usage and flexibility.
By the end of this course, learners will have a solid understanding of core linear data structures and how they are applied in real-world programming and algorithmic problem-solving.
