Question

Consider the two given functions:

int fun1(int x, int y)
{
if (y==0) return 0;
return (x+fun2(x, y-1));
}

int fun2(int x, int y)
{
if (x==0)
return y;
return fun2(x-1, x+y);
}

What will be the value returned by $\text{fun1}(4, 4)$ ____

Comments

17?

---

Answer must be 17

Answer 1

f1(4,4)->4+f2(4,3)->f2(3,7)->f2(2,10)->f2(1,12)->f2(0,13) return 13

in f1()->4+13=17

Answer 2

So return value  of  $\text{fun1}(4,4)= 17$
