Draw the uml and state diagram for an


Q.1. A) How many recursive calls are made from the call to fib (4) (not counting the original call)?

 

int fib(int n) { // assumes n >= 0

if (n <= 1)

return n;

else

return (fib(n - 1) + fib(n - 2));

}

B) Identify the recursive condition in the following code.

 

int fib(int n) { // assumes n >= 0

if (n <= 1)

return n;

else

return (fib(n - 1) + fib(n - 2));

}

C) Why does the best recursive method usually run slightly slower than its iterative counterpart?
