ACTUALLY DRAW THE STACK

$4.$ Show the stack with all activation record instances, including static and dynamic chains, when execution reaches position $1$ in the following skeletal program. This program uses the deep$-$access method to implement dynamic scoping.

$```$

void fun$1()\{$

float a;

$\}$

$...$

void fun$2()\{$

int b$,$ c;

$\}$

$...$

void fun$3()\{$

float d;

$\}$

void main$()\{$

char e$,$ f$,$ g;

$\}$

$...$

$```$

The calling sequence for this program for execution to reach fun $3$ is

main calls fun$2$

fun$2$ calls fun$1$

fun$1$ calls fun$1$

fun$1$ calls fun$3$
