Heap sort

Hi, This morning I have to present about one of sorting algorithm. The algorithm that i selected was Heap sort. Why? Cuz this is the only one I can remember since I studied when i was freshmen. All I can remember is, there are binary tree that we can use for sorting algorithm. Then, it's Heap sort.

Here is my simple video to show you how heap sort working, I use Max-Heap method to show you how it's work. Hope you like it.
