Heapsort can be seen as a better/faster version of Selection sort. Just like selection sort, we keep finding the next smallest item ...

We discuss the complexity of the Heapsort algorithm and argue that it is O(N log N). Compare this to selection sort, where the idea ...

We develop the code for a non in-place Heapsort using the heapq module in Python. For more details, please take a look at ...

Heap Sort visualized in yellow-to-red gradient — watch this efficient O(n log n) algorithm use a binary heap structure to sort data ...

Watching sorting algorithms is the fastest way to understand them. In this video, you'll see how each algorithm works — visually: ...

We will look at three problems -- Heapsort, Live Leaderboard and a Running Median. The problem of merging K sorted lists will ...

To fully appreciate the impact of the reduced complexity, we compare the run-times between Selection Sort and Heapsort.
