Quicksort is a popular sorting algorithm and is often used right alongside Merge Sort.Quicksort algorithm is easy in implementation.Quicksort is represented in three types of sotring algorithms.

3 ways for to implement and use Quicksort in Python
1.Divide and conquer.
2.In-place
3.Unstable
Divide and conquer Quicksort in Python
In divide and conquer quicksort splits the array into smaller arrays until it ends up with an empty array, or one that has only one element, before recursively sorting the larger arrays.
In place Quicksort in Python
In place Quicksort in Python does not create any copies of the array or any of its subarrays. It does require stack memory for all the recursive calls it makes.
Unstable Quicksort in Python
Unstable Quicksort in Python algorithm is called unstable because a stable sorting algorithm is one in which elements with the same value appear in the same relative order in the sorted array as they do before the array is sorted which unstable sorting algorithm cannot offer or cannot give guarantee that it could happen.For example: imagine you have several “Person” objects that have the same age,
i.e. Sachin 21 and Vaishanavi aged 21. If you were to use Quicksort on a collection that contains both Sachin and Vaishanavi, sorted by age, there is no guarantee that Vaishanavi will come before Sachin every time you run the algorithm and vice versa.
