Why should we learn Data Structure and Algorithms?

Most programmers need to realize the importance of data structure and algorithms as early as possible in their careers. The knowledge of this subject helps us grow as better programmers with problem-solving in computer science. We should never develop a belief to consider this merely a subject because it is much more than that! Think.

The part of the interview process of Tech Companies

Why tech companies test the knowledge of Data structure and algorithm during the interview process? The answer is obvious — these companies encounter problems daily that are complex and large on the scale of data, and they would like to hire a smart programmer who can solve those problems in minimal time, using the least number of resources. So the knowledge of Data Structures and Algorithms is a clear indicator of the programmer’s abilities in solving those problems efficiently.

An algorithm is a Technology!

The system performance depends on choosing efficient algorithms as much as on choosing fast hardware. Even applications that do not require algorithm directly at the application level…relies heavily upon algorithms. For examples:

Does the application require fast hardware? The hardware design used algorithms.
Does the application depend upon the user interface? The design of the user interface relies on algorithms.
Does the application rely on fast networking? Networking relies heavily on routing algorithms.

Overall, algorithms are at the core of most real-life applications. Just as rapid innovations are being made in other computer technologies, they are also being made in algorithms.

In the core of several library functions

Learning Data Structures and Algorithms might seem unnecessary in an age where we will be using library functions for 90% of our coding. Bug, why should we bother to learn the implementation when the implementation is hidden behind an abstraction? In such a situation, we must learn data structures and algorithms to understand the logic behind the behavior of these abstractions. If we don’t then, we will eventually apply them in a way that will hurt you.

Algorithms are beautiful!

Algorithmic logic is part of the beautiful pattern of nature and our real-life activities. There is immense satisfaction when we visualize working our way to an understanding of them. They are the ultimate brain teasers; Compact, simple pieces of logic mesh perfectly to perform a single task.
