Thank you so much for this. I'm sorry about the loss of your friend. Obviously his loss is a loss to the entire programming community. Your videos have helped me so much.

Btw those of you who are saying that the person who speaks in the video died, its not true. The narrator is Animesh Nayan. The person who passed away is Harsha S, he is only the co-founder of this channel and not the content creator. That being said, RIP Harsha S. India's best competitive programmer

Guys guys! PLEASE STOP THIS NONSENSE! Harsha who is *no more* is not the one talking in the video. Harsha was mostly working on the website part and also a genius in programming. The one who made most of the videos in Animesh Nayan who is still alive and working for Google apparently. Animesh is probably busy with his day job, he is a father now and may be isn't finding time to make new videos. I still wish he completes the series. Long live Animesh! You are like a programming god for us.

One more thing: Facebook post about Harsha's death is from June 2014; this video was published in February 2015. You guys learn how to use pointers but can't grasp a concept of chronology? That doesn't compile.

Great video. Feedback here: There is an issue with the weighted graph adjacency matrix - its not symmetric across the diagonal for the last vertex (H). The (7,3) value is shown as 6 whereas it should be 11. Similarly (7,4) (7,5) and (7,6) are shown as 11 (instead of 9), 9 (instead of 4) and 4 (instead of 6) respectively

There seems to be some confusion about what "Space" means in space complexity as you give an example of persistent disk storage. When we speak of space complexity it's not in terms of "disk storage" but "memory" - and to those yet uninitiated this can lead to big confusion going forward. It is true that personal computers can easily have ~ 2 TB of storage, but when you start talking about 2 TB of memory (RAM) - that's where the problem lies.

at 8:11 he talks about using a Hash table for the vertex list so you wouldn't have to linearly scan it to find an index given a vertex string name. I understand that you'd use Name-Index as Key-Value pairs: So, you could simply enter 'F' and it would return 5. My question is this: Once you obtain index 5 and consult the adjacency matrix at index 5 you find that index 5 is connected to 1 ('B') and 7 ('H'). But to find out that 1 = 'B' and 7 = 'H' wouldn't that be inefficient since you would have to scan your hash map using the values (i.e. the indeces) rather than keys (i.e. string names) ??
@devanarayanj6689
@devanarayanj6689 3 жыл бұрын
Why can't we use the keys(string names) of the B and the H to look for the indices in the hashmap? The search query will probably list their names as such wouldn't it?
