Algorithms and Data Structures Tutorial - Full Course for Beginners

In this course you will learn about algorithms and data structures, two of the fundamental topics in computer science. There are three main parts to this course: algorithms, data structures, and a deep dive into sorting and searching algorithms.

By the end, you will understand what algorithms and data structures are, how they are measured and evaluated, and how they are used to solve problems.

This is why good professor matter. I don't even know how to code yet, but the course is so interesting, I watched 46 min without even realized it.

[shantanuraj]

The future of clean, clear, coherent precise education starts with videos like this. More success and good wishes to people who make such videos and for free to the general public. This is one genuine and sincere way of serving humanity and educating people. Kudos and thanks for this wonderful video. Much love

[mubasharali]

What a course it's been. Learned the basics in a very fun way. When i started, just wanted to take an idea of dsa. But now learning and making notes side by side. Hats off to uh 💯

[cherolphoshoko]

This is such an amazing video!! So much value, I wish most courses had this same amount of quality! Thank you for this!!!

[easysolve]

I love this course! Brilliant and an instructor I can understand.

[amaniadore]

These lessons are high quality, clear, & concise. Everyone hit the tip jar if you can. Good job.

[utkarshrastogi]

You guys are doing great work, giving free education to us!

[napzzz]

Love Treehouse!! This is so awesome to see. I took some of their FSJS content and loved it. Highly recommend!

[bhargavpandya]

Extremely simplified explanation... very easy to follow along and understand every single Thank you very much for this!

[elbartout]

If anyone like me lost it at the final 3 lines in merge_sort() @4:00:00, make note that 'current' and merge.head point to the same Node object for the first pass of while-loop. When current.next_node is reassigned to a non-None value that first time, merged.head.next_node points to the same value. Hope this helps

[summa]

I understand that thinking in algorithms makes coding much more approachable. You guys did a great job

[kingrush]

I finally found someone that speaks my language . I completely understand every word. I completely understand everything word that your saying without rewinding back multiple times. Your the first that I would consider mentor

[sanjaysimon]

Thank you so much for this amazing tutorial!
I’ve been struggling with algorithms and data structures for a while now, but your explanations and examples made everything so much clearer.
I really appreciate the time and effort you put into creating this course.
Keep up the great work!

[pkasdovi]

I have never seen in my entire life someone who explains stuff like this omg..this is crystal clear..he is so clear that I have no questions.that is amazing.😱👏🏿👏🏿👏🏿wow
