    Default Calculating the Running time

    I have a problem like this:

    In terms of N, what is the running time of the following algorithm to compute X^N

    Java Code:
    public static double power(double x, int n)
      double result=1.0;
      for(int i=0; i< n; i++)
      return result;
    How would I go about solving that?

    Default Running time?

    You mean how long it would take to solve the ecuation? Like how many millisecs it would take? You want to time it?


    EDIT: I forgot to mention that you are not using the "x" variable that's passed as a parameter to the method. I'm pretty sure it has to be used in the method somehow...

    Difficult? This is Mission Impossible, not Mission Difficult. Difficult should be easy.

    just use start_Date = new Date();

    //ur code

    and end_Date = new Date();
    calculate running time as :end_date - start_Date.(in ms)
