Question

I cannot get this to work in IntelliJ

import java.util.Scanner;

public class Fibonacci {

    public static int fibonacci(int n) {
        if (n <= 1) return n;
        return fibonacci(n - 1) + fibonacci(n - 2);
    }

    public static void main(String[] args) {
        Scanner in = new Scanner(System.in);
        int n = in.nextInt();
        System.out.println(fibonacci(n));
        in.close();
    }

}

Answer 1

import java.util.Scanner;
public class Fibonacci {
  public static int fibonacci(int n) {
    if (n <= 1) return n;
    return fibonacci(n - 1) + fibonacci(n - 2);
  }

  public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    System.out.print("Enter value for n: ");
    int n = in.nextInt();
    System.out.println(fibonacci(n));
    in.close();
  }
}

$\color{blue}It \;is \;working \;as \;expected. \;You \;have \;to \;give \;the \;value \;for \;n \;to \;get \;the \;fibonacci \;result\;$
