Can someone hand trace this basic recursive function? Please hand-trace and show me all the steps. I do not understand how this works.
Expected output is:
The output is:
Message 3
Message 2
Message 1
Message 0
Message 0 is returning.
Message 1 is returning.
Message 2 is returning.
Message 3 is returning.
Homework Answers
Explanation: Generally the recursive calls are stored in stack of computer memory. stack follows Lat In First Out strategy. First the method call Message (3) is stored in stack and consequently Message(2),,Message(1),Message(0). Then recursive calls stops because times=0. Now Message(0) is on top of the stack and message(3) is at bottom of stack. while returning functions the stack top Message(0) is invoked first and so on and finally Message(3) is invoked last.so the returning calls are in reverse order.
