ANSWER IS ACCEPTED ONLY IF TYPED

A process has three physical memory frames and executes the following sequence of references to pages of virtual memory: 1, 3, 2, 1, 4, 2, 5, 3, 2, 1, 5.

All three frames are initially empty. Execute the page replacement algorithm and find the number of page faults that occur when the replacement algorithm is:

FIFO replacement

LRU replacement

A friend claims that he has identified some page replacement strategy that results in 5 pages faults for the sequence above. Is he right or not?
