When does quick sort take more time than merg sort?

Quick sort runs the loop from the start to the end everytime it finds a large value or a small value while in merge sort starts from the first position of the array and assembles the large or small numbers in one side in just one loop so its more faster than quick sort

Who is better quick sort or merge sort?

Statistically both MergeSort and QuickSort have the same average case time: O(nlog(n)); However there are various differences. Most implementations of Mergesort, require additional scratch space, which could bash the performance. The pros of Mergesort are: it is a stable sort, and there is no worst-case scenario. Quicksort is often implemented inplace thus saving the performance and memory by not creating extra storage space. However the performance falls on already sorted/almost sorted lists if the pivot is not randomized. == ==

Why is quick sort and merge sort called stable algorithms?

Quick sort is not stable, but stable versions do exist. This comes at a cost in performance, however. A stable sort maintains the order of equal elements. That is, equal elements remain in the same order they were input. An unstable sort may change the order. In some cases, the order of equal elements is of no consequence, but when two elements with different values have the same sort key, then order can be important.


Which sorting is best shell or merge how?

It depends how many elements there are and which gap sequence you use in your shell sort. Using Marcin Ciura's gap sequence, both algorithms will yield roughly equal performance at around 500 elements. With fewer than 500 elements, shell sort is generally faster, while merge sort is generally faster with larger sets, particularly large sets of disk-based data.

Stack is not a way to perform quicksort, it is a tool used to implement recursion.
