Given the system in part $1,$ beginning from power on$,$ the following byte$-$addressed cache references are recorded.

$0,4,16,132,232,160,1024,30,140,3100,180$ and $2180$

For each reference, list $(1)$ its tag, index and offset $(2)$ whether it is a hit or miss, and

$(3)$ which bytes were replaced $($if any$).$

What is the hit ratio?
