Data Structures and Algorithms in Python

Why need Data Structures?

Raw building blocks
- array, linked lists, trees...
Definition: Building blocks or raw materials for any software programs
Use right data structure for a problem
Data Structures - containers storing data in a specific memory layout
Array vs Dictionary (Hash Map) Memory Visual:
- Dictionary uses Hash Map
  - There is a key that gives and address of a bucket, which gives access to an element
