. A process has a memory reference pattern as follows:

                                                                        1 3 1 2 3 4 2 3 1 2 3 4

The above pattern (which represents the virtual page numbers of the process) repeats throughout the execution of the process. Assume that there are 3 physical frames. Show the paging activity for a True LRU page replacement policy. Show an LRU stack and the page that is replaced (if any) for the first 12 accesses. Clearly indicate which accesses are hits and which are page faults.
