Data Structures and Algorithms

Data Structures - It's a way to organise data in order to enable it to be processed in an efficient time.

Examples:
Consider some fruits, as example. It depicts how organised data can be useful.

Fruits not organised

Organised Fruit

It will be easier to pickup fruits from second basket instead first. Same happens with data structure, we organise the data before processing.

Common Data Structures:

• Array
• Linked List
• Stack
• Queue
• Tree
• Hashing
• Graph

Algorithms:

Set of rules to be followed to solve a problem.

Consider an example where the scattered fruits are first structured, and then followed steps to make them ready to be served.
