Assume that a virtual memory is managed using a buffer pool. The buffer pool contains five buffersand each buffer stores one block of data. Memory accesses are bydiskblock ID. Assume thefollowing series of memory accesses takes place:

5 2 5 1 2 3 6 5 9 3 2 4 1 5 9 8 1 5 3 7 2 5 9 1 0 4 6 8 5.

For each of the following buffer pool replacement strategies, show the contents of the buffer poolat the end of the series, and indicate how many times a block was found in the buffer pool (insteadof being readinto memory). Assume that the buffer pool is initially empty.
