One common check in processing strings in C is to determine if a particular character is $$white$-$

space$($a space, carriage$-$return, newline, or tab$).$ That code looks like:

$1$ int isWhitespace$($char c$)\{$

$2$ return c $==\text{'}\text{'}||$ c $==\text{'}\backslash$r$\text{'}||$ c $==\text{'}$

$\text{'}||$ c $==\text{'}\backslash$t$\text{'}$;

$3//$ hex: the four char values above are $0$x$20,0$x$0$d$,0$x$0$a$,$ and $0$x$09.$

$4//$ dec: the four char values above are $32,13,10,$ and $9.$

Below we show an $($accurate$!)$ rv$64$ implementation of the above source code. Note both the

input and the output are in register a$0.$ Explain, in English, succinctly and clearly, what

the assembly code is doing. The more specific and detailed the answer, the better
