Java Data Structures and Algorithms Masterclass (Udemy.com)

Great course covers full range of DSA concepts. Conceptual animations are excellent, But they should also be animated alongside while you code. It is hard to grasp the codes for which case the code is being written without seeing the animated case aside. Exercises are comparatively tough than how easily instructor animated the concepts. You should have used more animation while coding and make us prepare step by step for the exercises. I would be totally happy even if I had to watch long time videos, but I could crack exercises fast. So my expectations to the instructor: ->while coding animate beside. so that we can visualize the code easily. ->Make videos and animations such amount that, exercises can be solved easily. ->Animate for exercise solutions also. ->Use whiteboard if necessary, where cases are tedious to animate. Satisfied with course, highly recommended for interested deep learners.

I am currently studying up to the circular doubly linked list in data structures. It has been incredibly insightful to dissect how data structures are implemented in memory, their overall structure, and the underlying code. However, I have noticed some minor errors in the code. For instance, in the deletion process of the doubly linked list, the condition if(location >= size) for deleting the last element does not seem valid. I believe it should be if(location >= size-1). When the condition you mentioned is used, an error occurs while trying to remove the last node, the 3rd location, in a list of size 4. In the video, setting the location to 9 passed without any issues, but setting it to 3 results in the code falling into the else condition. Moreover, I have reservations about the method for removing all nodes in a doubly linked list. The lecture suggested that all references should be set to null in a loop before removing the head and tail. However, it appears that the nodes are removed even without this loop, merely by setting the tail and head to null. I would appreciate if you could verify this aspect.

The DSA in Java certification course on Udemy provided an exceptional learning experience. The instructor's teaching style was clear and practical, making complex concepts easy to understand. The hands-on approach, with coding exercises and quizzes, helped reinforce the knowledge gained. While some topics could have been covered in more depth, the course overall exceeded expectations, and the reviewer highly recommends it to aspiring Java developers. The Udemy platform was user-friendly, allowing for flexible learning at one's own pace. The reviewer gives the course 4.5 stars out of 5, expressing satisfaction with their personal learning journey.

Very nice for being so broad, using Java, and demonstrating algorithms with animations. Extremely valuable to me.. but.. One and a half star less because of poor code quality (lots of repetitions, poor optimization, cryptic variable names like i, j, etc.), and for sometimes not coding what was just explained in the animation (such as in the quick sort algorithm, in that the teacher just doesn't use the left and right pointer logic he just explained in the animations). I strongly suggest using this course in association with the "Cracking the coding interview" book, so that you have access to high quality coding solutions and a more advanced perspective in contrast with this course.

Good & wide range of topics covered which was the main reason I decided to go for this course. Content is good but when it comes to coding samples showed in the demo, there are many small mistakes, which can be critical if you're learning for the interview purpose. Some examples from the recent lectures I'm watching, 1. Lecture - Collision Resolution Technique - Linear Probing(insert) - Method - rehashKeys Issue - usedCellNumber should be reset to 0 when creating new Hashtable with double size as we are reinserting all elements 2. Lecture - Collision Resolution Technique - Linear Probing(search, delete) Issue - in delete method usedCellNumber should be decreased by 1 when deleting element from hashtable Along with such kind of issues, there are many inconsistencies, for ex, in the Bubble sort method array param name is 'arr' and inner loop is 'i -> j' but in the next Selection sort lecture method array param name is 'a' and 'j -> i'

The course is great, it has examples for each topic. In addition, the explanation of each topic is graphic and very detailed. In general, an excellent course with very good detailed explanations, mostly step by step. Not only that gives many concepts but also the way to use them. It is worth buying it, one of the best courses I have bought to be able to have the basic concepts when it comes to a code challenge or to program with excellence.

I just love how simply Elshad explains every convoluted topic. I love the simplicity of the course. Being a Computer Science graduate and software developer, this course has been handy in revising all the topics in utmost detail. However, explaining certain cases like, for example, why the loop is going till "array.length-1-i" using a dry run table could be more beneficial for the non-tech background students.

So far the course is decent to get some understanding of the basics and fundamentals. The only thing that I found somewhat frustrating is that most of the crucial lectures or in places where something important is being implemented via code, the tutor just moves on a very rapid pace and people who are not familiar with coding in general might not grasp what had happened. While making assumptions during coding any important part of the lecture I would assume we get some pictorial explanation side by side to clear our doubts.

Sometimes I struggled to understand the instructor due to the accent, but it was never enough to hinder me from learning and I know that is not something that can be helped so it should not detract from the course review. This course was amazing. I learned a lot of things that I never realized even though I took these courses in my own college programs. I was very impressed the entire time and enjoyed all of the lectures and exercises. Even when facing difficulties finding the solution I knew that I could look back on the lecture and find a way to solve the problem through that. Thank you for doing this course. It was very helpful!

See You knocked out recursive functions. broke into three steps. I used to get fear on proceeding with recursive functions, as it get over complicated . but you break those things into 3 universal steps and loved it. Don't worry , soon you will get more learners and your hard work will get a right fruit. "Please Revise Your CAPTIONS [SUBTITLES], it has lot of errors.. very hard to understand while fast forwarding... hope you will make that in future"
