Data Structures Complete Tutorial in Java | Stack, Queue, Linked List, Array, Hashing | @SCALER

What is DSA?
DSA stands for Data Structures and Algorithms. It refers to a set of techniques and methods used to organise and manipulate data in a computer program. Data structures are a way of organising and storing data in a way that enables efficient access and modification, while algorithms are a set of instructions that perform a specific task or solve a problem.

What is data structure?
A data structure is a way of organising and storing data in a computer program so that it can be accessed and manipulated efficiently. It defines a set of rules for how data is organised, how it is accessed, and how operations can be performed on it. Examples include arrays, linked lists, and trees.

What is an algorithm?
An algorithm is a set of instructions for solving a problem or performing a task in a computer program. It defines a series of steps or procedures that must be followed in order to achieve a desired outcome. Algorithms are used in a wide range of applications, from search engines to robotics.

Types of DSA
There are many types of Data Structures and Algorithms (DSA) including arrays, linked lists, stacks, queues, trees, graphs, hash tables, and sorting and searching algorithms. Each DSA has its own strengths and weaknesses and is suitable for different types of data processing and storage needs.

Applications of DS
Data Structures have a wide range of applications in computer science, including database management, algorithm design and analysis, operating systems, artificial intelligence, machine learning, and web development. They are used to store, organise, and manipulate large amounts of data efficiently and effectively, enabling faster and more accurate processing of information.

The fact that I have my DSA mid exam on monday and the audacity to binge watch this rn so I can ace- but hats off to you sir for clearing my concepts. Hoping to ace my exam.

[taushutk]

really a great insight in data structure

[This.Object]

Woahhh what a way to start the day let's gooo

[SumedhaJain-fevr]

I am a second year b tech student and today I completed this whole lecture
Thank you so much sir for this amazing content

[RochaNahuel]

Thanks for this bro, greetings from Argentina.

[kaifansari]

Thank you so much for the wonderful video! It's really easy to understand, filled with great information, and has real-life examples. I appreciate it a lot. I just wish I had the funds to join SCALER

'Two dimensional Array Input' has been repeated twice in the video. I am really liking the content, and your teaching style. especially how you give the coding example after explaining the concept.

[manikantakatakam]

Sir, if there are any material's they will be good to learn more.

[reetkhanchandani]

Hi, can you please give a real world example of Hashset ?

[aakhildasz]

Anyone in 2024 is this video still helpful, also suggest me if there is any video or channel where i can master dsa in java

[chelsHQ]

Is this a good video for someone who is starting out in programming? please let me know

[bencilinjohn]

I have one doubt.
I have completed only diploma. My age 29. I dont have any experience in IT related. I would like to move in data engineer job. It is possible? Is there any certification course to get data engineer job?

Please advise me

[ashisharya]

Can we please have the same video in a different language like Python, JavaScript, C# or Golang.

Thanks,
Ashish Arya
