Write a RISC$-$V MCU assembly language subroutine that converts a binary value in register x$10$ to a $4-$ digit BCD stored in the lower four nibbles of register x$11.$ The binary value will never be greater than $9999.$ Make sure your subroutine does not permanently change any registers other than x$11.$ Also include a brief but complete written description of the algorithm you used in your solution. For this problem, don$$t use the double$-$dabble algorithm. Minimize the amount of code you use in your solution.
