Consider the execution of this LEGV$8$ instruction: SUB X$3,$ X$7,$ X$9.$ Below is its binary representation $($the corresponding decimal is $1703182563)$:

bits

Assume that this instruction is stored in address $20($i$.$e$.PC)$ in memory, $x7=x9=5.$ Write down the values $($in decimal$)$ of the inputs and outputs of the components labelled with $($a$)$ to $($v$)$ and their number of bits. If a value is unknow, put the symbol $"?$
