• A. What is the hit ratio for

              for(i=0;i<100;i++)

                        x=A[i]+100;

• A. No of time block 0 is modified.

Comments

Yes I considered that as well ceil(100/8) ==>13 not sure :) .

@pream sagar  can you provide the answer

0,8,16,24,32,40,48,56,64,72,80,88

THESE ARE indexes which are replaced why we count A[96] also so i think only 12 time block 0 is modified
