QUESTION $4$

Consider the following code.

vara$=0,b=0$;

function computex$()\{$

var $a=4$;

varb$=1$;

$a=$ computeY $()$;

$a=a-2$;

return a;

$\}$

function computey $()\{$

$b=a+b+5$;

return $b$;

Suppose there is no other code available to run, other than what is shown above. Answer the following

questions a$)-$b$)$:

a$.$ What value will combuteX$()$ return?

b$.$ What value will computeY$()$ return?
