    Why do I like professor Abdul’s videos:
    1) He speaks clear English.
    2) Articulate, makes pauses.
    3) Straight to the point. No unnecessary fillers.
    4) More importantly, excellent explanations.
    Thank you sir!

    I just realized that I've lived in a DFS-like way all my life. I start a task, then hop on to the next and quit the first one, then hop on to the third, then go back to the second and then to the first. How have I lived w/o knowing this until now :D Especially true when cleaning the house :D

    Not one to write TH-cam comments, but Abdul Bari makes the best algorithms/data structures videos BY FAR. He is my go-to for anything CS-related. His videos are the best study materials I can find.

    Thank you again for the lecture, this was very helpful to me watching again as I did not understand the variations in depth and breadth the first time. I am liking the binary tree example very much to show that the linear order of the nodes (their sort order) is arbitrary (no pun). There is so much content on this channel, very educational and clear. Thanks

      Literally it would make more sense to swap the tuition cost to take my D&A course at my university with his Udemy course price.
