Lecture 1: Intro to Programming &
Flowcharts
CodeHelp - by Babbar
Introduction
Hello everyone! My name is Love Babbar and I would like to
welcome you all to CodeHelp. 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.
