Can someone explain me this code with comments so I understand each line processed public class Test { public static void main(String[] args) { System.out.println(power(2, -3)); System.out.println(power(5, 3)); } private static double power(double x, int n) { if(n == 0) { return 1; } else if(n < 0) { return (1.0/x) * power(x, n+1); } else { return x * power(x, n-1); } } }
