Stack is not a way to perform quicksort, it is a tool used to implement recursion.
A stack is implicitly sorted by hierarchical nested order. It does not make sense to sort a stack. Do you mean a list? If so, please ask the question again.
Yes, that's how quick-sort works.
Quick Sort
Yes, Quick Sort is an in-place sorting algorithm.
To efficiently use a stack to sort elements in a data structure, you can follow these steps: Push all elements into the stack. Create a temporary stack to store the sorted elements. While the original stack is not empty, pop an element from the original stack. Compare the popped element with the top element of the temporary stack. If the popped element is greater, push it onto the temporary stack. If the popped element is smaller, keep popping elements from the temporary stack and pushing them back onto the original stack until the temporary stack is empty or the top element is greater. Repeat steps 3-6 until the original stack is empty. The elements in the temporary stack will now be sorted in ascending order. By following these steps, you can efficiently use a stack to sort elements in a data structure.
When you want to sort an array.
Quick sort is more efficient for large datasets compared to selection sort.
Although quick sort has a worst case time complexity of O(n^2), but for sorting a large amount of numbers, quick sort is very efficient because of the concept of locality of reference.
quick sort is a divide and conquer method , it is not dynamic programming

quick sort
Because the quick sort can be used for large lists but selection not. selection sort is used to find the minimum element ,but quick choose element called pivot and move all smaller nums before it & larger after it.
