data structures and algorithms

For every aspiring software developer, getting a job in a product-based company is a dream come true. You can also get one. Yes, you heard it right! You can also become an SDE and get a handsome salary by following a few steps. DSA is a very important concept that has to be covered in these steps. As we all know Data Structures and Algorithms play an important role in software development, and you should be well aware of it.

DSA is the basic fundamental or building block of software development. Also, in most coding interviews, DSA is asked very frequently. You can build the most optimized solution if you’re good at DSA. The best way to learn is by reading through the best course on DSA. In this blog, we’ll be going through some of the best courses which you must definitely know.

These DSA courses cover all the basics to advanced concepts which could be used while implementing an application. Without much ado, let’s explore some of the best Data Structure and Algorithms courses.

What is DSA?

Data Structure and Algorithms, referred to as DSA, is the building block of software development. The best advantage is you can use DSA in any programming language. This is applied to bring an optimized solution, in problem-solving, and enables developers to write efficient code. Also, it helps you to work on memory and time optimization.

Every company, be it product-based or service-based conducts technical interviews in which asking DSA-based questions is mandatory so as to check the problem-solving ability of an individual. The more good a person is in DSA, the higher the chances of cracking the coding interviews.
