Question $4$

Consider the following code segment:

if $a==b$ :

print $(($:${?}^{**}{W}^{*}\}$

else :

print $({?}^{n}x")$

if $b==c.$

print$("Y")$

else :

print $("Z^{na})$

If $a,b$ and $($c$)$ are all $0$ then the output generated by this code segment is:

$($w$)$

followed by $r$ on the next line

followed by $r$ on the next line

followed by $x,$ on the next line, followed by $y$ on the next line
