Best Educational Channel Ever...Ty I can sleep in lectures because rather than hearing their things i learn way faster and proper by watching ur videos.
Thanks a lot Patel :)
You are a great man and more better than proffessors in my college, I have learned a lot from you . I felt like I was waste fellow , I couldn't understand data structures, algorithms and pointers
even if I had studied many times. but after watching your videos ,those concepts became easy .only because of you dude. you are a life saver,thanks a lot.But wanna see you back in you tube, why don't you upload more videos to save people like us.
I read somewhere in one the comments in his videos that he has passed away some time back, due to an accident. It is so unfortunate, his vids still help people to this date :(
@@Abhinavneelam I read it was an accident, don't know much other than that :(
oh god. man...:'( Someone has to continue what he started.
@@vivekkekuda he didn't passed and currently he is working in google as software dev engineer .his name is Animesh nayan ,founder of myCodeschool. however he started this journey with Harsha Suryanarayan -the great coder india ever produced till date and was the Lord among coding community .Unfortunately passed away in hit and run accident .After that Animesh also quit this journey mid way
#RIP The great Harsha
@@manishkumar3902ya dude you are right ❤
You sounded sad when you said there was no special name for an undirected graph.
+airloaf I laughed at that part and thought the same thing.
+airloaf lol
lol :))
It's a tragedy
Oh man, I thought I was reading too much into that haha
in search of gold we lost the diamond... If Animesh starts posting videos again ... the real happiness begins
He did this because no one else was doing it that time, but now he is a google employee, adding more value to the world.
@@RandomSerialKiller i read some posts that he died in an accident RIP
You're a wonderful teacher! Love the diagrams. Nothing old-school or boring here. I look forward to more of your videos. Well done.
this is the best introduction to graph I've seen so far
Best explanation ever on graphs. Love how you explain it with examples. Well done!
What a decent language and elegant way has been used to explain the matter....
Love it❤️
best channel for learning programming...even any1 like me who dont know programming can easily understand everything by watching your videos...thanx ..
You are so didatic and constant paced, my friend. Thank you.
I was struggling with my data structures assignment. I watched the 50 minute lecture over and over and still didn't get it. This video is a life saver and I can finally get on with the assignment.
I had to prepare for an interview and needed to brush up on some old forgotten information. Your videos fantastic and I found that my knowledge came flowing back again. So thanks very much for taking so much time to put together such a great set of information!
Clear and simple! This amazing teacher gives "to the point" explanations, with just the right amount of detail. Thank you very much :)
This is the most cogent and easily understandable explanation of basic computer science I have seen. I look forward to watching the rest of your videos.
Excellent teaching. This will help me get an understanding of the upcoming lesson so I don't struggle with the concept when I begin to code. Thank you!
Came for a refresher on these things and will probably end up watching your videos all day. Your videos really hit all points and are delivered so well, Thank you:)
8:50 "I can show only of them because I'm short of space" LOL the hidden sarcasm
Great introductory video to graphs. I really liked the way you defined the mathematics of ordered and unordered pairs and connected all the ideas together. Excellent work!
From watching your videos I know that you are a very detailed teacher. You didn't left anything unexplored, all my doubts are answered in the video a second later after I doubt it!
Like why ordered pair, you tell what it is. You tell that order of the name of each vertex doesn't matter which is what I was doubting about.
Keep this way of teaching further!
One of the best explanation I have ever seen about graph. This video stands out because real world examples given. Neat stuff!
Hats off to the quality of this one and related tutorials!
Thank you. Of all the CS instructional videos I have seen, yours are by far the most conscise and well-explained
I appreciate your passion and interest in making these videos.
It is really very helpful. Thanks a lot.
Please upload more videos on graphs, heaps and hash table.
is there any plans to upload C++ videos?
Each of your videos are priceless. Thanks so much.
Thank you so much for this simple introduction, in just 17 minutes I got to know what graphs are about and what are the use cases of graph, LOVE IT
"If I am your friend, you are my friend too." :D
only if this was true
Not in C++
Not on instagram😂😂
He's so sweet
Doubly linked list
really helpful in learning.I have never come across a great channel like your's

watching these videos and then reading through the comments feels like reading a time capsules. It is a real wierd feeling. The old posts in the blogspot and the website gives a lingering feeling of emptyness. Thank you animesh for these videos. :)
where is animesh sir?
Excellent job! Very clear explanation.
Thanks you so much! Looking forward for hash maps!
I hope you upload videos about graph traversal and searching. Thank for the videos we aprecciate

Your videos are really helpful , Thanks a lot.
Pleae keep uploading a new videos..your channel is helping me incredible on my college study..thank you very much!
great explanations man, well done!
Thanks for this amazing video. Do you have videos on hash table?
this is madness! thanks for the video!
Simply brilliant tutorial.
As always superb. I'm excited about your new series on graphs. Looking forward to dijkstra's algorithm, bfs, dfs, topological
sorted, connected components, is_graph_cyclic, all pairs shortest path, and minimum spanning trees.
Honestly Ella needed friends more than Rama.
Sam Berg hahaha true.. The example was not realistic.. *pun intended
Sam do you know Tom bcoz I am big fan of Jerry
🤦♂
lol 😂😂
Thank you! A way i like to think of the difference between digraph and graphs is that digraph are like instagram where you can establish a connection with someone by following them and a graph is like facebook where you have to friend a person. Facebook, the other person has to accept the request and for instagram, you can just follow them (assuming the account is public). Ofc in reality it is more complicated but this is a basic way to think of it.
Awesome content sir! Please continue the series with much more interesting topics like heaps AVL trees and Advanced DS sir. Hatsoff to ur content.Helps us a lot.
Good Explanation. Keep up the good work. Thank you
It wasn't exactly what I was looking for but very educational. I learned a lot
