Which of the following is a common sorting algorithm?

• A. Binary tree
• B. Quicksort
• C. Linear search
• D. Hash function

Answer: (B)

Quicksort is indeed a well-known sorting algorithm that plays a significant role in computer science and programming. It employs a divide-and-conquer strategy to efficiently sort arrays and lists by selecting a 'pivot' element and partitioning the other elements into two sub-arrays—those less than the pivot and those greater than it. These sub-arrays are then sorted recursively, which allows the algorithm to achieve an average-case time complexity of O(n log n), making it suitable for large datasets. The effectiveness and efficiency of Quicksort have led to its widespread adoption in various applications, including standard libraries in many programming languages. While other choices relate to data structures and algorithms, Quicksort specifically addresses the need for sorting data, distinguishing it from the alternatives provided.
