use the formula: k mod n to locate the block no.
all 8 are misses.
now,there are 4 conflict misses: 3 in block no.0 and 1 in block no.1
in block no. 0: 4 with 0;8 with 4;0 with 8
in block no. 1: 1 with 9
there are 7 compulsory misses(all references except the last 0 which is being referenced for the second time). note that compulsory misses are those which are referenced for the first time that's why these are also known as FIRST REFERNCE or COLD-START misses also.
thus, answer = 8+7+4 = 19.
