Question

Write static <T> void quickSort(T[] array, Comparator<T> cc)

Implement the version that picks pivots at random. This makes it a randomized algorithm and expect it to run in O(nlog⁡n) time.
Remember that the Comparator<T> interface in Java defines how we can compare objects of type T. The interface expects the existence of a method

int compare(T o1, T o2)

which compares o1 and o2 for order. More specifically:
- if o1 < o2, then compare returns a negative value;
- if o1 == o2, then compare returns 0 (this should be consistent with .equals);
- if o1 > o2, then compare returns a positive value.
