Q4. Consider the following page reference string of a process. Assume the process has 3 frames. Second chance (assume reference bits are cleared after every 6 references). Show the memory state (the pages in memory and their reference bits values) after each page reference. Also indicate which reference causes a page fault. 3543562523425427473
