Note: Questionl is a programming question. Implement LRU, FIFO, Optimal page replacement algorithm in any programming language. Consider the following page reference string: 1, 2, 3, 4, 2, 1, 5, 6, 2, 1, 2, 3, 7, 6, 3, 2, 1, 2, 3, 6 1. Assuming demand paging with four frames, how many page faults would occur for the following replacement algorithms? LRU replacement FIFO replacement ' Optimal replacement
