Fibonacci Number

Write a program which prints $n$-th fibonacci number for a given integer $n$. The $n$-th fibonacci number is defined by the following recursive formula:

\begin{equation*}
fib(n)= \left \{
\begin{array}{ll}
1　 & (n = 0) \\
1　 & (n = 1) \\
fib(n - 1) + fib(n - 2) & \\
\end{array}
\right.
\end{equation*}

Input

An integer $n$ is given.

output

Print the $n$-th fibonacci number in a line.

Constraints

$0 \leq n \leq 44$

Solution in JAVA (judge verdict: Wrong Answer)

import java.util.Scanner;

class Main {
	static int Fibonacci (int n) {
		
		return ( n == 0 || n == 1)?n:Fibonacci(n - 2) + Fibonacci(n - 1);
	}
	
	public static void main (String[] args) {
		Scanner scan = new Scanner (System.in);
		int n = Fibonacci (scan.nextInt());
		scan.close();
		System.out.println(n);
	}
}
