6.4 Quick Sort

Quick Sort is a widely used and well-known sorting algorithm that is known for its efficiency and outstanding performance. It is named after its ability to quickly sort large arrays or lists of items. Like Merge Sort, Quick Sort also employs a divide-and-conquer strategy, but it utilizes a unique approach.

The algorithm begins by selecting an element, known as the 'pivot', from the array. It then partitions the other elements into two sub-arrays based on whether they are greater than or less than the pivot. This in-place pivot selection and partitioning step requires only a small amount of additional space.

One of the key features of Quick Sort is the ability to sort a vast number of items in a short amount of time, making it a popular choice in practice. Moreover, the algorithm's versatility ensures that it can be applied to a wide range of data types, from integers to strings. In addition, Quick Sort's use of in-place sorting and divide-and-conquer...
