Write no recursive versions of the functions in Exercises 11-15.

Exercise 11

Determine what is calculated by the recursive functions

unsigned f(unsigned n)
{

   if (n == 0) return 0;

   // else
return n * f(n - 1);
}

Exercise 12

Determine what is calculated by the recursive functions

unsigned f(double x, unsigned n)
{

   if (n == 0)

   return 0;

Exercise 13

Determine what is calculated by the recursive functions

unsigned f(unsigned n)
{

  if (n < 2)
  return 0;
 // else
 return 1 + f(n / 2);

}

Exercise 14

Determine what is calculated by the recursive functions

unsigned f(int n)

{
   if in < 0)
  return f(-n);

   if (n < 10)

   return n;

   // else

   return f(n / 10);

}

Exercise 15

Determine what is calculated by the recursive functions

unsigned f(int n)

{
  if (n < 0)
  return f(-n);

  if (n < 10)

  return n;

  // else

  return f(n / 10);

}
