Question

Heapsort (as the code is written in this module) is a stable sorting algorithm. Recall that a stable sorting algorithm maintains the relative order of records with equal keys.

a. True
b. False

Answer 1

Heapsort is not a stable sorting algorithm as it does not maintain the relative order of records with equal keys.

Step-by-step explanation:

Heapsort, as the code is written in this module, is not a stable sorting algorithm.

A stable sorting algorithm is one that maintains the relative order of records with equal keys. In the case of heapsort, it involves building a heap data structure and then repeatedly swapping the root element (the largest value) with the last element in the heap and heapifying the remaining elements.

Since heapsort involves swapping elements and does not explicitly consider the original order of equal keys, it is not a stable sorting algorithm.
