PCs' main memory is a combination of read-only memory (ROM) and random-access memory (RAM) (read-only memory and random access memory, respectively).

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.

Both read-only memory (ROM) and random access memory (RAM) make up the main memory of a personal computer (read-only memory and random access memory, respectively).

The primary memory of a personal computer is comprised of both ROM and RAM (read-only memory and random access memory, respectively).
