So now we are going to begin a proper, step by step demonstration of the Heap Sort Algorithm in Python. Remember the workings of the heap that I mentioned earlier. Building the Initial Heap This array of 8 numbers is what we will be sorting with the Heap Sort Algorithm. Let’s take th...
Write a Python function to merge two sorted lists with heapq and then compare the result with the manual merge algorithm. Write a Python program to use heapq.merge to merge two sorted lists and then output the merged list in a single line. Python Code Editor: Have another way to solve th...

Heapsort is an efficient sorting algorithm. In this tutorial, we are going to see how to write a python program for heap sort algorithm.
Heap Sort is a popular and efficient sorting algorithm in computer programming. Learning how to write the heap sort algorithm requires knowledge of two types of data structures - arrays and trees. In this tutorial, you will understand the working of heap
