1. Data Structure &
Algorithm
1.introduction to Data Structure and
algorithm

2.  What is Data structure?
 What is Algorithm?
 Why we need DS?
 What are prerequisites of DS?
 Types of data structure.
 Requirements?

3. what is Data structure?
Data Structure
Raw facts,figures. + Arrangement/sequence.
Definition:
“a special way to organizing and sorting data(Management)
so it can be use in efficient way”
“Sequence of step to solve a given problem”
e.g:
Making a cup of Tea.
what is Algorithm?

4. Algorithm

6. Why we need
DS?/why we study
it?
To represent data in more
efficient way.
• Less time
• Less space(memory)
To build software in this
way it consume less
power and take minimum
time .
Prerequisites??
Previous courses:
⋄ C/PF
⋄ C++/Oop
⋄ JAVA/Oop
Requirements??
 Time to perform
each operations
 Programming
effort
 interest
Most important you

Linear:
• Array
• Link list
• Queue
• stacks
Non-linear:
• Tree
• Graph
