Finally a decent tutorial on the deletion/removal of the root in a Max Heap! THANK YOU SO MUCH! Couldn't find this anywhere else on Google/Youtube.

This is the best explanation I've ever seen. All I ever wanted to know is what a max and min heap are lol.

You are the best. You explain things so clearly and make it so easy. I pray I pass this exam!

I have an exam on Friday that includes heaps, you've definitely saved me from doing terribly. Appreciate it!

sirunknown

Thank you for the very clear explanation.

Question: when you removed the 40 from the top of the list, how did you determine that it was the 8 you had to replace it with ?

Why the 8 and not the 3 or whatever ?

I'd like to know, if I was using a min heap would I take the smaller of the two children or is it still the bigger of the two?

Great vid helped me out a lot but like ma ria said please in the name of god upload some stuff on stacks queues, linked list that would help out a lot thanks!

What if we had the same heap without 1, 3 and 8, and then wanted to remove the value 15 or 13. Would we not then put 19 there and have to look at the parent if it was smaller (as in this chase 19>18)?

JacobJNilsson

thanks for the beautiful presentation.

Not clear how to select element to remove, says only "top-bottom left to right", if just so shouldn't he move 3 (and not 8) when it removes 40?

enrico

hi, i have quick question, right side must be greater, why here in left sub tree 13 < 15, is it rule??
