Why data structure is important for programmer ?

Answer 1

Martin Taylor With all respect, I should have framed my answer better.

Those millions and billions of entries was an example of the google search. Because there are so many entries there and when we try to get a result, it returns in no time.

Also arrays, linked list, stack, queue and tree data structures etc. use those 3 operations and are widely used.

It is all about how you arrange the data so that you can do the above mentioned efficiently. So sorting comes into picture.

I'm sorry if I am wrong, but you answered the question well👍

Answer 2

Always remember that there are just these 3 basic operations for which you generally need data structures.
1) Insertion
2) Deletion
3) Retrieval

You need to make these process as efficient as you can because you are dealing with data in millions or billions of entries.

Also sorting plays a major role.
