Show the stack with all activation record instances, includingstatic and dynamic chains, when execution reaches position 1 in thefollowing skeletal program. Assume bigsub is at level 1.
Show the records and where pointers point to for dynamic andstatic linkages/chains of reference
function bigsub(){
function a(flag){
function b() {
...
a(false);
...
} // end of b
...
if (flag)
b();
else c();
...
} // end of a
function c() {
function d() {
... <------------------------1
} // end of d
...
d();
...
} // end of c
...
a(true);
...
} // end of bigsub
The calling sequence for this programfor execution to reach d is bigsub calls a
a calls b
b calls a
a calls c
c calls d
