Comment on Tutorial : Recursion in java By aathishankaran

Declaring int result within the method will change the value of result each time you run the method, there is an alternative method :



class Factorial {



     int fact(int n)

 {

     if ( n ==1) return 1;

     return  n*  fact (n-1);

    }

}

 

therefore taking the additional variable 'result' was completely unnecessary. Im in the twelfth grade.
