1. Introduction to Data Structures and
Algorithms
What is a Data Structure?
A data structure is a way of organizing and
storing data efficiently so operations like
searching, insertion, and deletion can be
performed effectively.
Common Examples:
Arrays
,Linked Lists
Stacks
Queues
Trees
Graphs
What is an Algorithm?
, An algorithm is a finite sequence of steps to
solve a specific problem.
Characteristics of a Good Algorithm:
Correctness → Produces correct results.
Efficiency → Uses minimal resources.
Clarity → Easy to understand.
Finiteness → Must terminate.
Generality → Works for all valid inputs.
