Question: Which of the following statements about Quick Sort is true?

Options:

Correct Answer: It can be implemented using a linked list

Solution:

Quick Sort can be implemented using a linked list, but it is not stable and does not always select the median as pivot.

Which of the following statements about Quick Sort is true?

Which of the following statements about Quick Sort is true?

Step 1: Understand what Quick Sort is. Quick Sort is a sorting algorithm that works by selecting a 'pivot' element from the array and partitioning the other elements into two sub-arrays according to whether they are less than or greater than the pivot.
Step 2: Learn about linked lists. A linked list is a data structure where each element (node) points to the next one, allowing for efficient insertions and deletions.
Step 3: Know that Quick Sort can be applied to different data structures, including arrays and linked lists. This means you can sort a linked list using Quick Sort.
Step 4: Understand the concept of stability in sorting algorithms. A stable sorting algorithm maintains the relative order of records with equal keys. Quick Sort is not stable because it can change the order of equal elements.
Step 5: Learn about the pivot selection in Quick Sort. The pivot can be chosen in various ways (first element, last element, random element, etc.), but it does not always select the median value, which is the middle value in a sorted list.
