For every professional programmer, data structures, and algorithms (DSA) are the two most fundamental areas to master.  The more efficient you are in data structure and algorithms, the better you can evaluate the efficiency of an algorithm, make your code scalable, and effectively utilize memory. 

Importance of mastering Data Structure & Algorithms:

Data Structures and Algorithms are the building blocks to design and develop an efficient software application. Data structures store objects and allow their manipulation, and they can be –

  • Linear – arrays, stacks, linked lists, or queues
  • Nonlinear – trees, graphs, tables, or sets

On the other hand, algorithms help in defining clear steps and conceptualizing solutions in terms of distinct steps in a process. Data Structures and Algorithms alter the system by providing accessibility of data and increase the efficiency of the product. They also aid in analyzing the time and space performance of algorithms. 

The difference between average and great programmers is often due to knowledge of data structure and algorithms.  Whether you are beginning your programming journey – or going back to explore the fundamentals, mastering DSA would make a world of difference. At Naukri Learning, we have put together an updated list of free data structures and algorithms courses to help you master these topics.
