15. Quicksort

The chapter focuses on the Quick sort algorithm, developed by Tony Hoare, which efficiently sorts an array by partitioning it into two subarrays based on a pivot element. It highlights the advantages of Quick sort over Merge sort, especially regarding memory usage, and explains the recursive nature of the algorithm. The chapter also elaborates on partitioning strategies and their significance in ensuring optimal sorting performance.
