Problem $4(16$ Points$)$

Assume $s1$ has been initialized to a signed integer and hence it might have a negative value.

a$)$ The following RISC$-$V code increments $s1$ by $1$ only if the current value in $s1$ is within a

specific range. What is this range?

b$)$ Explain why the following RISC$-$V code does the same task as the code in part $($a$)$ above.

Support your explanation with examples.
