Redefine the method power (Display 11.3) so that it also works for negative

exponents. To do this, you also have to change the type of the value returned to

double. The method heading for the redefined version of power is as follows:

/**

Precondition: If n <>

Returns x to the power n.

*/

public static double power(int x, int n)

Hint: x-n is equal to 1√(xn).
