Question: Which of the following statements about Heap Sort is true?
Options:
It is a stable sort
It is an in-place sort
It is faster than Quick Sort
It requires O(n^2) time in the worst case
Correct Answer: It is an in-place sort
Solution:
Heap Sort is an in-place sorting algorithm, meaning it requires only a constant amount of additional space.

Questions & Step-by-Step Solutions
Which of the following statements about Heap Sort is true?
Step 1: Understand what Heap Sort is. It is a sorting algorithm that uses a data structure called a heap.
Step 2: Learn about in-place sorting algorithms. These algorithms sort the data without needing extra space for another array.
Step 3: Realize that Heap Sort rearranges the elements within the same array, which means it does not need additional space for sorting.
Step 4: Conclude that since Heap Sort only uses a small, constant amount of extra space (for variables), it is considered an in-place sorting algorithm.
