This document summarizes a session on data structures and algorithms. It begins with definitions of algorithms and examples of writing an algorithm to find the largest number in a list. It then defines data structures and algorithms (DSA) and explains their importance in efficient problem solving. It also provides examples of applications of DSA like search engines. It classifies different data structures and provides assignments on algorithms problems. Finally, it discusses preparing for interviews, including examples of questions and suggestions for effective responses.

1. Road to GDSC Greater Noida Institute of Technology

2. Welcome to the third session
Technical Skills

3. Introduction to
Data Structure Algorithms
&

4. What is
Algorithm?
● Algorithms are step-by-step
procedures for solving
problems.
● It takes a set of input(s) and
produces the desired output.

5. For Example :
Write an algorithm
to find the largest
number in a list of
numbers.

6. ● Step 1: Start
● Step 2: Begin from the first number in the collection Step 3: Assign it
to a variable called "largest".
● Step 3: Take the next number & compare with the "largest" variable.
● Step 4: If the current number is larger than the "largest" variable,
update the "largest" variable to the current number.
● Step 5: Continue Step 4 and 5 until all numbers have been compared.
● Step 6: Return "largest"
● Step 7: End
Algorithm to find the largest number in a collection:

7. What is DSA ?
DSA stands for
"Data Structures
& Algorithms."
Data structures
are different
ways of
organizing and
storing data.
Each data
structure has its
own strengths
and
weaknesses.
In DSA,
algorithms are
used to solve
problems
efficiently.

8. Is DSA important to
learn?
If yes, then Why?

9. Importance of DSA
Efficiency Problem Solving Optimization Scalability

10. Applications of
DSA
Search Engines Social Media
Network
Maps and
Navigation Apps
E-Commerce
Websites etc.
