Consider the buffer replacement policies: 'Most Recently Used' and 'First in First Out': i. Construct an example (sequence of read or write requests) that, for the same query set, the 'First in First Out’ buffer replacement policy performs the worst with one buffer size and performs the best with another buffer size. Justify your answer and explain why if it does not exist.
