$(15$ points$)$ Given below $($on the left$)$ is a partial trace of MAR accesses. In addition, you are given $($on the

right$)$ the contents of several memory locations, PRIOR to any execution of the code. Do not assume any$-$

thing about the initial state of registers. The PC is originally at x$3000.$ Note, the code does not do anything

meaningful, so don't bother understanding it$.$

Hint: The MAR holds address of memory locations, which can hold Instructions, Addresses or Data.
