The following page-reference string:

1, 2, 4, 3, 2, 5, 4, 2, 4, 2, 1, 3, 2, 3, 1, 3, 6, 1, 6, 4.

Main memory with 3 frames of 1 kilobyte available and they are all initially empty. Complete a figure, similar to Figure 8.14(in the slides or textbook), showing the frame allocation for each of the following page replacement policies:

a. Optimal

b. Least recently used

c. First-in-first-out

Then, find the relative performance of each policy with respect to page faults.
