code: public static int max(int a, int b, int c) {
      int ma;
      ma = a;
      if (b > ma) {
        ma = b;
      }
      if (c > ma) {
        ma = c;
      }
      return ma;
    }
docs: max() that works on three integers.  Like many of the other max() functions in this class,
  doesn't perform special checks like NaN or -0.0f to save time.
  
  @return The maximum of three int values.
