Lecture 1: Intro to Programming & Flowcharts
Introduction
Today, we will be starting our DSA course and in this lecture, we will be
discussing flow charts, pseudocode, and programming languages. We
will also talk about the importance of using them. If you already have
knowledge about these topics, feel free to skip ahead.
Getting Started with DSA
If you are new to programming, grab a pen and paper and let's dive in!
The intent of this course is to prepare you to easily solve any DSA
question that comes up in online tests or interviews. You should be able
to provide optimal solutions to these problems.
Problem:
Given a set of values, how do we approach the problem and write code
to solve it?
Solution:
● Analyze the problem: Before writing any code, it's important to
understand the problem and break it down into smaller,
manageable parts. This involves identifying the inputs and
expected outputs, as well as any constraints or requirements.
● Choose an appropriate algorithm: Once we have a clear
understanding of the problem, we can choose an algorithm that fits
our requirements. This may involve researching different algorithms
and their time and space complexities.
● Write pseudocode: Before writing actual code, it's useful to write
out the steps we need to take in plain English. This helps us to
organize our thoughts and ensure that we are on the right track
before we start coding.
● Write code: Finally, we can write the actual code to solve the
problem. This may involve debugging and testing to ensure that the
code works as expected.
