Write a program in Java 17
import java.io.*;
import java.util.*;

public class Main {
public static void main(String[] args) throws IOException {
BufferedReader reader = new BufferedReader(new InputStreamReader(System.in));
// Read the integer input
int n = Integer.parseInt(reader.readLine());

// TODO: Increment n by 1

// TODO: Decrement n by 2

// TODO: Double the resulting value of n

// Print the final value of n
System.out.println(n);
