public class fibonacci {
public static void main(String[] args) throws Exception {
    BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
    System.out.print("Enter value of n: ");
    String st = reader.readLine();
    int num = Integer.parseInt(st);
    int f1=0,f2=0,f3=1;
    for(int i=1;i<=num;i++){
        System.out.println(f3);
        f1=f2;
        f2=f3;
        f3=f1+f2;
    }
}
}
