1-(2 points) For the following C statement, what is the corresponding RISC-V assembly code? Assume that the variables f, g, h, and i are given and could be considered integers as declared in a C program. Use a minimal number of assembly instructions. f=(g- h) - (i + 5) 2-(2 points) For the following RISC-V assembly instructions below, what is a corresponding C statement? Assume f, g, h, i are in x18, x19, x20 and 21. sub x18, x19, x20 add x18, X18, X21
