How is developed a strategy that allows you to stabilize any sorting algorithm for an Array with n Elements with "O(n) additional memory"?
For instance, Heap-Sort Algorithm is unstable or Quick Sort depends on the Implementation for stability. This stability must only be provided with O(n) additional memory, not the other strategies.
I have tried this question for the whole day, but I…

Assume that we have an Mystery-Sort(A), which takes an array A of
length n as input, sorts the numbers in A in non-decreasing order, and returns the sorted array.
