Merge sort space is O(n) not O(1)

Need to update merge sort space complexity to O(n)

It was odd to me that merge sort stats here are "better" than quick sort in every way - whereas Quicksort is used everywhere in practice, not Mergesort.

Why is QuickSort favourable over MergeSort in practice?

Quicksort is used bc is has better space complexity than merge. Merge should be O(n)
