Show the activation stack with all activation record instances, including static and dynamic links, when execution reaches Line #$19($write$($z$)$;$).$ Assume the activation stack begins at address $50,$ integers occupy two locations, addresses one location in memory, and the parameters are passed by value. Show your answer in $3$ columns, Address, value, and explanation $($describe rows meaning like what it is like main.result, A$.$staticLink, A$.$dynamicLink etc$)$

program main;

var result : integer;

procedure A $($x : integer$)$;

var aaa : integer;

procedure B $($y : integer, j : integer$)$;

begin $($b$)$

j :$=$ y $+5$

C$($j $+2)$;

end $($B$)$;

begin $($A$)$

x :$=$ x $-2$;

aaa :$=3$;

B $($aaa$,$ x$)$;

end $($A$)$

procedure C$($z : integer$)$;

var m : integer;

begin $($C$)$

result :$=$ z;

write $($z$)$;

m :$=$ z;

D$($m$)$;

procedure D $($x : integer$)$;

begin $($D$)$

x :$=12$;
