In this exercise, we will examine how replacement policies affect miss rate. Assume a two-way set associative cache with four one-word blocks. Consider the following word address sequence: 0, 1, 2, 3, 4, 2, 3, 4, 5, 6, 7, 0, 1, 2, 3, 4, 5, 6, 7, 0. Consider the following address sequence: 0, 2, 4, 8, 10, 12, 14, 16, 0

5.20.3 [5] Simulate a random replacement policy by flipping a coin. For example, "heads" means to evict the first block in a set and "tails" means to evict the second block in a set. How many hits does this address sequence exhibit?
