Question: Consider the following page reference string: 7 , 2 , 3 , 1 , 2 , 5 , 3 , 4 , 6 , 7

Consider the following page reference string:
7,2,3,1,2,5,3,4,6,7,7,1,0,5,4,6,2,3,0,1,4,3,5
Assuming demand paging with four frames. How many page faults would occur for the following replacement algorithms, and what the 4 logical pages in the memory at the end. In Optimal algorithm, if a victim page cannot be decided, use LRU to choose one.
