Write static void quickSort(T[] array, Comparator 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 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.

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.
