$(3$ points$)$ The NOT is an assembly operator that can be used in RISC$-$V assembly programs. However, NOT is not listed as a RV$32$I operator on page $104$ of the 'riscv$-$isa$-$spec.pdf$\text{'}$ on Canvas. This means that the NOT operator is translated into a different statement. What is the translation of 'not rd$,$ rs$1\text{'}$ in RISC$-$V ISA? Justify why the translation works correctly. $($Hint: look for 'NOT' in 'risc$-$v$-$asm$-$manual.pdf$\text{'}$ on Canvas.$)$
