1. 18.7 What does the following code do?

   

2. 18.8 Find the error(s) in the following recursive method, and explain how to correct it (them). This method should find the sum of the values from 0 to n.

   

3. 18.9 (Recursive power Method) Write a recursive method power(base, exponent) that, when called, returns

   
        base exponent
   
   

   For example, power( 3,4 ) = 3 * 3 * 3 * 3. Assume that exponent is an integer greater than or equal to 1. [Hint: The recursion step should use the relationship

   
        base exponent = base · base exponent – 1
   
   

   and the ...
