A process has been allocated $$3$$ page frames. Assume that none of the pages of the process are available in the memory initially. The process makes the following sequence of page references (reference string):
$$$1, 2, 1, 3, 7, 4, 5, 6, 3, 1$$$
If optimal page replacement policy is used, how many page faults occur for the above reference string?

A virtual memory system uses First In First Out (FIFO) page replacement policy and allocates a fixed number of frames to a process. Consider the following statements:
$$P:$$ Increasing the number of page frames allocated to a process sometimes increases the page fault rate.
$$Q:$$ Some programs do not exhibit locality of reference.
$$P:$$ Increasing the number of page frames allocated to a process sometimes increases the page fault rate.
