What is wrong with the following recursive sum method?  The method is supposed to sum up the values between 1 and x (for instance, sum(5)should be 5 + 4 + 3 + 2 + 1 = 15).
   public int sum(int x)
   {
      if (x == 0) return 0;
      else return sum(x - 1) + x;
   }
a.   The base case should return 1 instead of 0.
b.   The recursive case should return sum(x - 1) + 1 instead ofsum(x - 1) + x.
c.   The base case condition should be (x <= 0) instead of (x == 0).
d.   The recursive case should return sum(x) + 1.
e.   The method should return a boolean instead of an int.
