Write a RISC$-$V function to count some of the values in an array.

Your function should implement this interface:

int array$\_$sum$($int $*$array$,$ int count$)$

$($all $`$int$`$ values mean $64-$bit integers$)$

$`$array$`$ is the address of an array of $64-$bit integers, and

$`$count$`$ is the number of entries in the array $($so the total memory

used by the array is $`8\backslash$times count$`).$

For each element in the array, you should call another function

that I provide:

int predicate$($int element$)$ It will return $0$ if you should skip the element and $1$ if you should

add it to the sum.

Pseudo$-$code for this function might look something like:

$```$

int array$\_$sum$($int $*$array$,$ int count$)\{$

sum $=0$

for i $=0$; i $<$ count; i$++\{$

if predicate$($array$[$i$])\{$

sum $+=$ array$[$i$]$

$\}$

$\}$

return sum

$\}$

$```$
