DSA is a core concept in programming. It stands for data structures and algorithms. Any programming or computer science curriculum includes DSA as a subject. In fact, data structures and algorithms are two of the core concepts of computer science.
In this article, we will explore the 10 best data structures and algorithms courses that are presently available for learners. These courses will guide you in starting out with DSA as well as advance with the same if you already have developed some proficiency with data structures and algorithms.
But before we start explaining these best DSA courses, let’s know data structures and algorithms a bit more in detail.
What are Data Structures and Algorithms (DSA)?
Both data structures and algorithms are two of the fundamental concepts associated with programming. Any aspiring programmer needs to have good knowledge of data structures and algorithms.
While algorithms are the processes or procedures through which we solve real-world problems, data structures are approaches to organizing, storing, and managing data in a program . Arrays, dictionaries, graphs, linked lists, lists, stacks, tuples, and queues are examples of data structures.
Different programming languages provide support for different types of data structures. A data structure in one programming language might not be available in another programming language. For instance, C++ and Java have arrays, but Python doesn’t.
