Course Description
This is an animated, visual and spatial way to learn data structures and algorithms
- Our brains process different types of information differently - evolutionarily we are wired to absorb information best when it is visual and spatial i.e. when we can close our eyes and see it
- More than most other concepts, Data Structures and Algorithms are best learnt visually. These are incredibly easy to learn visually, very hard to understand most other ways
- This course has been put together by a team with tons of everyday experience in thinking about these concepts and using them at work at Google, Microsoft and Flipkart
What's Covered:
- Big-O notation and complexity
- Stacks
- Queues
- Trees
- Heaps
- Graphs and Graph Algorithms
- Linked lists
- Sorting
- Searching

Her explanations are solid, and she leans towards explaining which topics are bound to come up in interviews. Also, in comparison with other courses, she also dives into algos like shortest path which is cool. ALSO she shows you how to write the stuff from scratch, including interfaces the classes use and the classes themselves. I recc

The resources are good and the explanations are quite clear, at least for most parts. They are well segmented into the concept, then the explanation of the algorithm, then the code implementation of it. However, the issue is that the team is small and they are releasing a multitude of courses, meaning that they do not respond to Q&As at all. If you are not okay with not getting any Q&A help, then this course is not for you. Would've been an easy 5 stars if the instructors are responsive to queries.

Very clear explanation so far on time and space complexity, Big O notation, LinkedList and Stack implementation.

quick get hands on prepare for interview this course meets just aptly for that requirement the balance of programming and theory is quite apt to keep engaged

Yes it was actually pretty good course. From basics to intermediate you will get to know about data structure.

Very difficult to understand for beginner.

Graphic and colors are bad.
By Akshat Gupta on 7/26/2020
It would be great if the instructor could explain some of the coding problems deeply like in case of binary trees. she did not explain the tree problems(code) thoroughly.
Apart from that I liked the course very much. Prior to that course, I did not have knowledge about DS but after doing this course I have got a good knowledge about DS. I recommend this course to anyone who wants to learn DS and also to those who wants to switch company and do not have knowledge about DS like mine.Yesterday I gave an interview and interviewer asked me the question of Parenthesis match which is available in the stack section.
Kudos to the instructor Janani...

Simplest explanations to the complex subject!!
By Anthony A on 7/13/2020
I did not like this course. The tutor does not seem passionate about her craft (teaching), she just seems like a driven businesswoman who wants to churn out courses.

Very useful course.
