Implementing a Heap in Java - Part 2

This video shows how to implement the heap data structure in Java, one of a series of lessons in data structure and algorithms. In this second part, the algorithms for sift up and sift down are traced on the array storage scheme, putting together the building blocks for the code. Following this, a Heap class implementation is discussed, including code for insert and delete.

I want to let you guys know that, I don't usually comment on youtube videos. But I got to let this off my chest. This guy here, so much better than my shitty lecture and his useless material. Explanation is clear and understandable.

Great great great! 
Best Heap tutorial I've seen so far, with no recursion at all. Great job!

[adarozer]

Thank you so much Mr Venugopal. Your teaching is very clear and good. Regards from Istanbul .

[codingandmathvideos]

Your explanations are truly amazing. Very clear and easy to understand. I wish you 
would do more videos: breadth first search, topological sorting, Bellman ford algorithm, prim's and Kruskal's algorithm.

Never found such a easy and clear explanation for do check for part 1

[ThakurArjun]

The best tutorial on heap I have ever come across, thanks a lot.

[Chaitanya.Yeluri]

I watched several videos before this one. The is the best explanation I have seen so far. Thank you Sir for this great video.

[zeroliuxiyuan]

Very detailed tutorial with cleared tutorial. Best heap tutorial I have ever seen!

[likevrr]

can't expect more than this....many thanks for the clear explanation...

[anelemadonda]

you are the best lecturer ever. I wish you did assembly language tutorials.

[mehakhed]

Excellent explanation. Best so far of all I came across.

[sabio]

To the point and precise explanation. Thank you. Looking forward to more videos like this.

[rmishra]

Awesome way of explaining . I have been looking for a simple implementation and finally found it .

[nohjrd]

That's absolutely brilliant.  These tutorials are so clear and easy to follow.
Thanks so much!

[vidyasagardindu]

Excellent ! Well organized in explaining the concept. Running with the Basic Structure of the tree to the array representation and finally to the code.  No need to remember much..Concepts are digested easily ! Thank you very much..Wishing you all the best !

I really liked this video. I could write my own heap class very easily after watching this. It would have been great if you had similar videos for a HashMap

[alokjain]

simply awesome, easy to understand.... look fwd for other videos

[cutealiens]

These videos were extremely helpful. And you even posted the code right in the description! Thanks a lot, professor. Sorry I never got to take a class with you.

recently I had a phone screen and I did not know about Heap datastructure and after accidentally hitting your video I just realized how easy it would have been had I seen this video before.

Sesh, thank you so much. Your video and explanation they made the job. I've watched many others but your's are incomparable clear and easy.
Now i've liked to add some flags to the code to compare with another sort method.
