Question
Consider the following algorithm:
int f(n)
/* n is a positive integer */
if (n<=3) return n+1
int sum = n
sum sum + T(n-1) +T(n-2) - T(n-3)
return sum
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. You can work on
paper and submit an image of it.
