I was given this question:
a Given page reference strings: 1,2,3,4.2,1,5,6,2,1,2,3,7,6,3,2,1,2,3,6. Compare the number of page faults for LRU, FIFO and Optimal page replacement algorithms, assume 4 frames are available. b Which method can you rank as the best and why?
I have tried solving it myself but keep getting stuck.
I even used tools like chatGPT and Gemini but they both kept giving contradicting values every time I regenerate the response.
