About the Course

In this course, you will learn new data structures for efficiently storing and retrieving data that is structured in an ordered sequence. Such data includes an alphabetical list of names, a family tree, a calendar of events or an inventory organized by part numbers. The specific data structures covered by this course include arrays, linked lists, queues, stacks, trees, binary trees, AVL trees, B-trees and heaps. This course also shows, through algorithm complexity analysis, how these structures enable the fastest algorithms to search and sort data....

Really good course so far. Using VSC + git bash on a Windows 10 machine for the programming assignments, and the web-based compiler for the challenges. Really good experiences so far.

My favorite Coursera specialization! Responsive staff, lectures are very clear, assignments are both challenging and educational (closely related to lecture materials). Thank you!

I suppose I take issue with the quizzes and the use of Cloud 9.

Although passable by doing research outside the class materials, many of the quiz questions ask the students to apply knowledge never explicitly mentioned in the lectures. For example, the code for accomplishing the heapify down algorithm was shown, but the heapify down algorithm was never explicity defined. Instead, a brief story suggesting how it generally works is provided. If the vision for this course is to provide some perspective on a data structures course that was previously taken, or a unique take on data structures to supplement the student's prior knowledge, so be it. I can recommend the "Ordered Data Structures" course as an orientation to much of the important information in the field, but that's the best I can do. It would be best to clearly orient the student at the beginning of the class, mentioning that it will require outside knowledge not provided here.

Although Cloud 9 is described as optional, it's really mandatory to complete the coding challenges, and it would be fair play to simply say so. The make file provided to prepare the assignment for submission is tailored specifically to Cloud 9, and NOT to use Cloud 9 for the assignments would require the student to understand the complex requirements (never described in any detail) for preparing the code for the testing algorithm, and write a really complex make file. Just say, "Use Cloud 9", and save the student the uncertainty and time wasted trying to cobble together a solution on VisualStudio or whatever.

I have many positive comments. I feel that the professor knows his stuff, and great care was taken to prepare the lectures and assignments to get students to engage meaningfully with data structures covered here. I had to work harder than someone who'd just finished a "Data Structures and Algorithms" course -- and that's fine, because I needed to do the work! I think the professor did well in previous course as well. Props to my C-U homies! (I'm a UofI and Urbana High School graduate.)

Looking forward to the third course.

The lecture material and assignments provide a good overview. It's difficult enough to be a challenge for those who can grasp software engineering topics and well-supported with a lot of code and automated challenge question tools plus automated grading of more involved coding assigments. I would recommend supplementary reading and research as the lecturer takes some specific tangents that leave out some general cases. By the end of the course, I gained an appreciation for ordered data structures that I believe will be applicable in modern software development, including my current employment.

Coding exercises are good, but definitely need to read up on material for deeper understanding. This also helps with the exercises (makes them go a bit smoother and more enjoyable). Would be beneficial if there were a brief summary of notes on some of the topics. Would definitely recommend coding from scratch the data structures and basic algorithms taught, it helps solidify understanding. Provides a good introduction into data structures topic.

The content is good in terms of the topics that are covered. Binary Tree, BTree, AVL and Heaps are fundamental data structures and are well explained. The code files provided contain lots of comments to thoroughly explain the content. Also the videos explain the concepts well. The assignments could have been more challenging but the reviewing the code files provides the challenge required.

Great course. I enjoyed it thoroughly. Again, I wish there was more than 1 programming exercise in the class as practice coding these objects is essential. I only wish we had more challenges to code these structures rather than simply picking up with heavily commented, pre-coded objects.

This was a very interesting class. I certainly learned about data structures but, for me, what I learned most was about recursion. I've heard of it, I knew it conceptually, but this is the first time I actually wrote recursive programs.

I found sessions for the first 03 weeks quite interesting and easy to understand. However, this is not the case for Week 4 - Heap. Hope that there will be more practical code samples to illustrate this problem.

The instructor has a nice engaging style. The lectures are a bit short for me. I wish the assignments had been more challenging. It felt like most of the work was already done. But it was a great refresher.

Very concise summary covering the most important topics in data structures. The last few lectures were over-summarized. It would be hard to understand the concepts with the material provided here alone.

It covers a lot of material in a short span of time, so retention is key. Make sure to take a lot of notes and give yourself some time to really process all the material from each week.

submitting the program assignments for the first time took long and the process was tideous . except that the course content and the instructors explaination all were excellent.

Really good course, Makes you understand the intuition of the data structures pretty clear. The exams and assignment for week 4 seems a bit rushed, Could have been better

Good quick introduction to ordered data structures. I think this course be well served with a bit more theory explaining the big O justifications.

The lectures are good and elaborate. Some of the exercises are very confusing though.

Overall a good introduction to data structures.

The material covered is explained very well, but it feels like these UIUC courses are light in terms of total material per course.

Great course. Although I believe that programming projects are too difficult to handle for someone without CS background.
