Consider the following algorithm: int f(n) /* n is a positive integer */ if (n <=3) return n int sum = f(n-1) if (n is even) return sum + f(n-2) else return sum + f(n-3) Trace execution of f(6) by drawing the recursion tree. Show all function calls (callers and called functions), and intermediate results; and show what f(6) returns. Make sure that you draw all subtrees even if some are identical

Question
Consider the following
int f(n)
/* n is a positive integer */
if (n <=3) return n
int sum = f(n-1)
if (n is even)
return sum + f(n-2)
else return sum + f(n-3)
Trace execution of f(6) by drawing the recursion tree. Show all function calls (callers and called functions), and intermediate results; and show what f(6) returns. Make sure that you draw all subtrees even if some are identical.
