3 year old video and he still likes the comments. Absolute mad lad :D
Using a syllabus to judge difficulty is like reading the ingredients to a Michelin Star meal and assuming it's easy to prepare since it uses simple ingredients. Preparation and execution are two different things. Switching topics, the class was taught by a professor with the lowest ratings in the school. Resources were seldom provided, ambiguous project/homework requirements, no feedback on work, very unforgiving grader, etc. The way a class is taught is a major factor in determining whether you pass or not. It's good that you're looking into these videos in advance which will provide you with a sort of insurance if you get a professor like I did (twice). @@Abdullah-ak231

It's been a stressful semester, but your KZbin materials have been the absolute most effective means for me to remediate my algorithm and data structures deficiencies. I just purchased both of your courses. I hope to be able to work on them over the summer, but even if I don't, I wanted to purchase your content to express my gratitude for the excellent free content you provide here on KZbin. I'll be suggesting your materials to my friends that are learning to code and trying to self-teach algorithms and data structures.

There is a small mistake at 29:41, when deleting 30 from the heap, 8 is swapped to the root. it should compare 16 and 20 to 8, and use 20 as the new root, thus 20 and 8 is swapping place. No further swaps are needed, resulting in heap in state 20, 16, 8, 15, 10.

In the video he compared index 3 with index 5. When actually index 3 can only be compared with either indexes 6 & 7. However, those nodes were deleted and replaced with previous maxes( index 6 of value 30) and (index 7 of value 50). The next deletion of 20 would render the tree to be 16, 15, 8, 10.

In heapify at last he did two iteration. Two is the size of tree here. So if number of elements are n we have to do log(n) iteration (Depends on case). So, going through each node will take n time and heapify will take logn time. Therefore time complexity should be O(nlogn) for heapify. Isnt it????

@jindagi_ka_safar3 жыл бұрын
Creating a Heap is inserting all the elements of a given array into an existing heap assuming the first element of the given array as the initial heap, where as Heapify is simply creating a CBT ( complete binary tree) with all the elements of the given array and then converting that CBT into a heap, by moving up from the last non-leaf node up to the root. Great explanation as ever.

As a PhD student in computer science, I use your tutorials to prepare for my PhD qualifier exam. None of my undergrad classes can be better than your videos!

Amazing! Especially when heap sort comes from delete a node, I just want to say, oh my god!!!!!!

Amazing explanation. I knew all the concepts before but still watched the video at 1.5x to the end because the explanation is so intuitive and clear. It seems magical to me that the same contiguous allocation of memory can function as arrays and heaps both with wildly varying time complexities for the same functions. Algorithms and mathematics in general is beautiful :) Will be donating something to the Patreon link as well to show my support for making education accessible to everyone. Everyone should give this guy a coffee to show appreciation for his time and energy to make awesome content.
