Apply the (1) FIFO, (2) LRU, and (3) optimal (OPT) replacement algorithms for the following page-reference strings:
Write a program that implements the FIFO, Optimal, MFU, and LRU page-replacement algorithms. Given a page-reference string, where page numbers range from 0 to 9, apply the page-reference string to each algorithm, and output the number of page faults incurred by each algorithm. Write your code so that the number of page frames in the page table can vary from 1 to 10. 1.0 Functional Requirements 1.1: Your program shall be run with the following: ./a.out Example: ./a.out datafile.txt 1.2:...
