Consider the following pseudocode:

int $i$;

int a$[3]$;

void fun$($int $x,$ int $y$

$x=x+y$

$y=x-y$

$x=x-y$

$i=0$;

$\}$

main$()\{$

$i=0$;

$a[0]=1$;$a[1]=2$;$a[2]=3$;

fun$($i$,$ a$[$i$])$;

println$($i$,$ a$[0],$ a$[1],$ a$[2])$;

$\}$

For each of the following parameter$-$passing methods, what would the code print?

$($a$)$ pass$-$by$-$value
