(C++) I need a quicksort algorithm implementation which returns the indices of the sorted array in an array without modifying the array itself: ie, Before sorting index : 0 1 2 3 4 5 values: 70 60 40 20 30 50 After sorting index : 3 4 2 5 1 0 values: 70 60 40 20 30 50 function returns an array with indexes: [3 4 2 5 1 0]
