What is the machine code $($in hexadecimal$)$ for the following RISC$-$V code, assuming it is assembled starting at address $\backslash (0\backslash$times $80\backslash )?$ For each instruction, show the memory address and include the instruction fields with their binary encoding.

$```$

addi x$10,$ x$0,16$

Again: add x$4,$x$10,$x$3$

and x$4,$x$10,$x$4$

sd x$4,12($x$1)$

bne x$1,$x$0,$Again
