Course Overview

Python Data Structures & Algorithms + LEETCODE Exercises

DSA + LEETCODE for Coding Interviews — Clear, Step-by-Step Animated Walkthroughs!

Welcome to Data Structures & Algorithms in Python

This course makes learning to code fun and makes hard concepts easy to understand.

How did I do this? By using animations!

Animating the Data Structures & Algorithms makes everything more visually engaging and allows students to learn more material - in less time - with higher retention (a pretty good combination).

I will use these visuals to guide you, step-by-step, through the entire course.

The course also includes dozens-and-dozens of Coding Exercises. So you can immediately put everything into practice as soon as you learn it (a very important step).

All of this will help you to feel more confident and prepared when you walk into a coding interview.

I have made several Free Sample Videos available for the course so you can see the difference the animations make.

Also, I am very active on the Q&A, so I will be with you every_step_of _the_way.

    The visualisations were very well done. Much of the course was well explained, and I think this was a good intro to DSA and LeetCode. However, some sections lacked much explanation, notably the LeetCode problems. There was also quite a bit of sloppiness in some of the solutions and explanations. Some of the "in-place" operations weren't actually in-place. Some of the provided solutions weren't optimal (e.g., lst.pop(n) might cause you to fail an interview). Also, requiring that the solution not write a peek method, and then violating encapsulation in the provided solution is very frustrating. Overall, I still recommend this course, but wish it was cleaned up, and detailed explanations were expanded, especially in the second half of the course.

    The content is detailed and explained well in the lecture videos. In my opinion the coding challenges are great and build you up well for implementing algorithms with Python along with variations to those algorithms.
