From 0 to 1 Data Structures & Algorithms in Java - Heap Sort Phase I-Heapify

The video tutorial covers the heapsort algorithm, emphasizing the need to understand heaps before implementing heapsort. It explains the two main phases: heapify and sorting. The heapify phase involves converting an unsorted array into a max heap in place, while the sorting phase uses the max heap to sort the array. The tutorial provides a detailed walkthrough of the heapify process, demonstrating how to maintain the heap property by sifting elements. The video aims to clarify the heapsort process through visual and logical explanations.

What happens to the size of the heap during the heapsort process?

How does the heapsort algorithm handle the sorted array during the sorting phase?

What is the significance of using a Max heap in heapsort?

Describe the steps involved in the heapify phase of heapsort.
