    This really cleared things up for me after struggling with the paper for an hour. Thank you!

    Best Johnson's tutorial on the internet. Thank you.

    Thanks for the clear explanation Tushar. I am working on a project and key point of it is to efficiently find all cycles in a directed graph. Your video conveniently comes in:) one thumb-up.

    Thank you very much for this video! It helped me a lot to understand the mechanics of both Tarjan's and Johnson's algorithms :)

    Thank you Tushar! This was very helpful, and showing the code at the end was amazing.

    thank you for a very clear explanation video. i have a question. when is leastVertex not startVertex? is it when startVertix is itself a scc?

    +Tushar Roy Thanks for all the great videos and simple explanations! These are great for anyone simply trying to understand how these algorithms work. If you could, for future videos, discuss the implementation of these algorithms in C/C++/Jaa i(as is the customary language used for Data Structure classes), and how it would work step by step; I think that would also help a lot for beginners who may not have the basics down yet.

      +Tushar Roy just kidding, I had seen your older videos and made this comment only about halfway through this video, thanks again!

    Hi Tushar, thanks for the videos. A question: Every time I delete a vertex from one strongly connected component, must I find again the new strongly connected component of the remaining vertexs? Thanks

    On the starting screen the edge 1->5 was not there.

    Tkank you for excellent work! But I was curious about how to find all circles of a certain range length (like in range 3 and 5) ?

    Hi again. I want to compile the program in java. So, I want to ask you something: do I only need JRE and eclipse?. I come from c++ and it is my first time with java :D. thank you a lot.

    Dear Tushar, what is the number of simple cycles in a digraph, any direct formula?

    Sir,
    Do we need to find strongly connected components? Isn't it only for optimisation?

      Cycles exists in only strongly connected graphs, so yes you need to find them first.
