Процесс разделения в алгоритме Quicksort состоит из следующих этапов:
Важно отметить, что Quicksort использует рекурсивный подход к сортировке данных, а также может работать на месте, то есть требует только ограниченное количество дополнительной памяти для выполнения разделения и объединения подгрупп.

Process of partitioning in Quicksort involves the following steps:Selecting a pivot element: Initially, a pivot element is selected from the array. Typically, the middle element is chosen as the pivot, although in some cases, a different strategy for selecting the pivot element may be used.
Partitioning the array: The remaining elements of the array are divided into two subgroups: one containing elements less than or equal to the pivot element, and the other containing elements greater than the pivot element. This process is carried out in such a way that all elements to the left of the pivot are less than or equal to it, and all elements to the right are greater than the pivot.
Recursive partitioning of subgroups: The partitioning process is then repeated for each of the subgroups until a base case is reached, where a subgroup consists of only one element or is empty. In this case, the subgroup is considered sorted, and the partitioning process stops.
Merging of sorted subgroups: The subgroups are sorted separately and then merged together in the correct order. In the resulting array, elements less than the pivot element are placed before it, and elements greater than the pivot element are placed after it.
It is important to note that Quicksort uses a recursive approach to sorting data and can work in-place, meaning it only requires a limited amount of additional memory for performing partitioning and merging of subgroups.
