Why Data Structures and Algorithms are Important ?

A lot of beginners and experienced programmers
avoid learning data structures and algorithms
because it's complicated and they think that
there is no use of all the above stuff in real life.

These concepts help to improve the problem-
solving ability of a candidate to a great extent.
