b$)(10$ points$)$ Find the shortest sequence of RISC$-$V instructions that extracts ${11}^{th}$ to ${16}^{th}$ bits

$($including both ${11}^{th}$ and ${16}^{th}$ bits$)$ of register $x5$ and uses the value of these bits to replace ${26}^{th}$ to ${31}^{st}$

bits of register x$6.$ You should keep the other bits of registers x$6$ intact. $($Caveat: Be sure to test your

code using $x5=0$ and $x6=0xfffffff.$ Doing so may reveal a common oversight$).$
