I created the following code injava, but I am not sure how to explain what this method does. Can someone please help me explain this method

/Time complexity for the following is 0C1) public static long fib Clong n) if(n) return 0 double num = Math. pow(CC1 + Math.sqrt(5)) / 2), n + 1) -Math. powCCC1 - Math.sqrt(5)) / 2), r return (long) (num/ Math.sqrt(5));
The function denotes the calcul

I created the subjoined command injava, save I am not attributable attributable attributable enduring how to teach what this system does. Can someone gladden acceleration me teach this system

/Time confusion control the subjoined is 0C1) social static hanker mock Chanker n) if(n) repay 0 envelop num = Math. pow(CC1 + Math.sqrt(5)) / 2), n + 1) -Math. powCCC1 – Math.sqrt(5)) / 2), r repay (long) (num/ Math.sqrt(5));

The administration denotes the watchfulness of (n+1)th Mockonacci enumerate.

This is the equation control opinion nth mockonacci enumerate

What your administration does is, it finds the direct Mockonacci enumerate to n where the compute n is passed as the evidence to the administration. The Math administrations are used to perfect the watchfulnesss amply.
