Extracted text: Exercise 6.26 Consider the RISC-V machine code snippet below. The first instruction is listed at the top. (a) Convert the machine code snippet into RISC-V assembly language. (b) Reverse engineer a high-level program that would compile into this assembly language routine and write it. Clearly comment your code. (c) Explain in words what the program does. a0 and al are the inputs, and they initially contain positive numbers, A and B. At the end of the program, register a0 holds the output (i.e., return value). 0x01800513 Ох00300593 0x00000393 Ох00058E33 0×01C54863 0x00138393 Ох00BЕОЕЗ3 0XFF5FF06F Ox00038533
