d) Page swapping is an essential element of virtual memory: two page swapping algorithms are the First In First Out (FIFO) and Least Recently Used (LRU) algorithms. Using a demand page system with 3 frames how many page faults will be generated by the following sequence? Clearly show how you arrived at the answer. Reference Sequence = [E, G, A, B, E, F, A, C, B, D, E, A, F)
