Description

Do you find yourself feeling like you get "stuck" every time you get a coding question? 


Welcome to Data Structures & Algorithms, Level up Course the only course that provides you an ultimate practice on problem solving process and helping you to take your data structures & algorithms to the next level.  The course is taught by an expert instructor Prateek Narang from Google, who is not just a software engineer but also has mentored thousands of students in becoming great programmers & developers.

The Course contains 25+ hours of interactive video content & dozens of coding exercises, teaching you the right tips & tricks in problem solving in a most concise way. Every problem discussion starts with a brute force approach, optimisations and ends with hands-on-coding video in C++ as well.

Here is what you will learn -

Problems on Data Structures

* Arrays, Strings, Vectors

* Hashing (Unordered Maps, Maps, Sets)

* Stacks, Queues, Linked Lists

* Binary Trees, BSTs, Heaps

* Graphs, Tries

Problems on Algorithms

* Brute force, Backtracking

* Sliding Window Algorithms

* Sorting, Searching, Binary Search

* Dynamic Programming Fundamentals

* Important Graph Algorithms

* BFS & DFS, Shortest Paths


Course exercises are in C++ but programmers having experience in one or more languages (C++/Java/Python/JavaScript) can definitely do this course, provided they have fundamental understanding of data structures. The course covers both breadth & depth of topics, diving deep where-ever needed. You will also learn how to apply techniques involving like - sorting & searching algorithms, sliding window, binary search, hashing which are very important for problem solving. For advanced topics like Dynamic Programming & Graphs, the course starts from the basics & helps you master these topics from the very fundamentals.

Unlike most instructors, I am not a salesperson or a marketer. My job is to help you build strong fundamentals in programming & be  a successful developer. Through Udemy, I am providing this course to you at a fraction of cost of its original cost, so that anyone who is interested to learn can take their skills to the next level. So I hope you sign up today, and I will see you in the course.

The value provided by this course is very high specially when you compare it's cost with other courses of its kind in the market.

Chaitanya6 June 2021

I was preparing DS and Algorithms since few years now on and off. But this is well structured and upon proper practice of all the patterns explained in this videos curriculum one can definitely crack a coding interview and develop a good problem solving nature (by practice). Thanks Prateek Bhai

Priyanshu5 June 2021

Coding Blocks videos of Prateek were better. There's a lots of things missing, like no complexity discussion at end of questions, and a kind of rush in sake of completing the course. But I believe Prateek will work on it as well in future to improve the quality. Talking about content, It's best out there, it's Prateek Narang after all. This course at such a price is steal deal.

Vinamr2 June 2021

This course by Prateek Bhaiya is actually amazing, IF you are someone who has done the basics of DS that is till Arrays and Recursion. This is the best course you could have asked for, interesting problems and way more interesting discussions on them. Have not found any course like this. Much love to prateek bhaiya for doing this!

Varun1 June 2021

First of all I would like to say Thank you prateek bhaiya... Dil se shukriya bhaiya apka... Apne aise pandemic situation m ham sab learners k liye itne kam cost m itna accha content provid karaya ...... Well structured course material . I think every student who want to learn something better should join this course. Bhaiya please keep providing these type of courses especially Competitive programming . Thankyou ?

I am working professional currently working in service based company.I want to switch to product based company.I have started implementing the problem set in my preferred language JAVA.The problemset and their explanation by Prateek sir is really top notch.In market this course will be easily selling around the price 10k.You can't get a better course at a better price than this.

Parika22 May 2021

Very good course, but strangely all discussion forum is crowded and polluted by people asking for adding new modules, thus due to that, doubts in existing course is taking longer to resolve. As far as content is concerned, its very good, Maybe an improvement can be to add a text file with time complexities of that question as a lecture resource so that we can verify ourselves.

Mahima22 May 2021

There was an indeed demand for good course of ds and algo , which u have satisfied . Thanks for explaining even simple things in detail. Future dev can learn everthing very easily.Kudos to your work.

Anish21 May 2021

This is the best dsa level up course.I would recommend this to everyone who has basic knowledge on how to implement data structures. Prateek Narang is one of the best mentor of dsa in the world. I have already done one course designed by him and he explains each and every concept in a very simplified manner which gave me confidence to participate in competitive programming challenges. Thank you so much.

Syed20 May 2021

i had been already taken your course on coding block ...but when i see u launch ur own course i purchase it .....happy learning

P
Prakhar20 May 2021

I have always been a fan of prateek bhaiya's style of teaching . Looking at him actually inspired me to teach my friends DSA and improving myself on the go . I'd say take this course if you have some base and you'll do wonders!

Greg19 May 2021

I don't usually give a rating so early in a course, but if the first 15 minutes is any indication of the what the rest of the course will be, this will definitely be a 5 star course. Problems are great and the explanations are even greater.

Vidushi18 May 2021

I have been trying to understand some advanced topics of DSA for the past one month and this course is like a life saver. It contains all the necessary problems with the most efficient solution.

Abhinandan18 May 2021

I am really enjoying your course because I am learning new things not only in advanced t topics but also the easier one . I don't know why I'm just loving your lectures. I am very thankful to you for making me to utilize my time in this lockdown.
