We have a process that has been allocated 3 page frames and initially none of the pages of the process are available in the memory. The following sequence of page references (reference string) is made by the process : 1, 2, 1, 3, 7, 4, 5, 6, 3, 1If Optimal Page Replacement policy is used,_______ page faults will occur for the above reference string.
