Why Interviewers mostly asks questions about Data Structures and Algorithms??

Question

Where Data Structures are used instead of storing data??

Answer 1

first of all it's because they just like to ask a lot of things that are not relevant. but as far as data storage structures and algorithms are concerned, this is the first thing a programmer encounters. the algorithm answers the question how to do it, the data structure how and where we will store it. this is fundamental programming knowledge
