Introduction to Data Structures and Algorithms

What is a Data Structure

Organizing, managing and storing data is important as it enables easier access and efficient modifications.

They are containers storing data in a specific memory layout.

Explanation

When you are building home you need certain building block and raw material such as bricks, wooden planks, rods etc. On top of that home building instructions are applied and we get home as result

Similarly, when we are building software, we need raw building blocks, which are, data structures, and on top of that code instructions are applied which operates on DS and as a result we get a software application

Data Structure implementation in different programming languages

Data Structure	Python	Java	C++
Array	List	Native array, ArrayList	Native array, std::vector
Hash Table	dictionary	HashMap LinkedHashMap	std::map
Linked List	N.A.	LinkedList	std::list
