The output for this program has been stated as 332.
How is it possible ?

f("123") is called. It calls f("23") twice, then prints "2".
f("23") calls f("3") twice, then prints "3".
f("3") doesn't print anything.

So "3" gets printed twice, then "2".

Whether you actually see anything is system dependent, because no
linefeed is printed at the end.
