All language subtitles for 2. Introduction to Data Structures

Hey welcome back.
1

So let's just talk with our First Lesson of data structures and algorithms but before discussing
2

any of the topic I would like you to understand term data structure and algorithm.
3

Now this consists of three different terms.
4

That is data then structure.
5

And then algorithm let's just understand what these three terms means and then understand
6

what this whole subject will do . Firstly
7

Let's just understand what is data.
8

Now, data is collection of raw facts.
9

Now the next terms is what is structure. Structure is arrangement or organization of related data.
10

So we can say , data structure is a collection of grouping of all the related data items and set of
11

allowed operations on those data items.
12

So next question comes in our mind
13

What kind of operations we are talking about.
14

So the set of operations can be insertion deletion updation searching or sorting.
15

Now the third term was algorithm .
16

What is algorithm ?
17

It is defined as the finite sequence of well defined instructions to solve a problem.
18

Well you need to understand one thing very clearly that before coding programmer approach is always to
19

define an algorithm.
20

why ? because an algorithm is always language independent which means that algorithm would be common.
21

whether you are coding in C /C++/ Java , any of the programming language but that doesn't matter.
22

So that is why, always firstly algorithm would be developed then flowchart and then a program.
23

So this is the hierarchy of developing a program . OK ,IN THE NEXT Lesson we are going to discuss that what types
24

of data structures do we have and where to implement which data structure.
