Problem: This is an interactive problem.

We hid from you a permutation p of length n, consisting of the elements from 1 to n. You want to guess it. To do that, you can give us 2 different indices i and j, and we will reply with p_{i} mod p_{j} (remainder of division p_{i} by p_{j}).

We have enough patience to answer at most 2 ⋅ n queries, so you should fit in this constraint. Can you do it?

As a reminder, a permutation of length n is an array consisting of n distinct integers from 1 to n in arbitrary order. For example, [2,3,1,5,4] is a permutation, but [1,2,2] is not a permutation (2 appears twice in the array) and [1,3,4] is also not a permutation (n=3 but there is 4 in the array).

Input

The only line of the input contains a single integer n (1 ≤ n ≤ 10^4) — length of the permutation.

Interaction

The interaction starts with reading n. 

Then you are allowed to make at most 2 ⋅ n queries in the following way: 

  * "? x y" (1 ≤ x, y ≤ n, x ≠ y). 



After each one, you should read an integer k, that equals p_x mod p_y. 

When you have guessed the permutation, print a single line "! " (without quotes), followed by array p and quit.

After printing a query do not forget to output end of line and flush the output. Otherwise, you will get Idleness limit exceeded. To do this, use:

  * fflush(stdout) or cout.flush() in C++;
  * System.out.flush() in Java;
  * flush(output) in Pascal;
  * stdout.flush() in Python;
  * see documentation for other languages.



Exit immediately after receiving "-1" and you will see Wrong answer verdict. Otherwise you can get an arbitrary verdict because your solution will continue to read from a closed stream.

Hack format

In the first line output n (1 ≤ n ≤ 10^4). In the second line print the permutation of n integers p_1, p_2, …, p_n.

Example

Input

Output

? 3 2

? 1 3

? 2 1

! 1 3 2

Solution (in JAVA):

Solution:
import java.util.Scanner;

public class Main {
	
	public static void main(String[] args) {
		
		Scanner sc = new Scanner(System.in);
		
		int[] ans = new int[10001];

		int[] vis = new int[10001];

		int n = sc.nextInt();

		for(int i = 1; i <= n; i++) {
			
			vis[i] = 0;  ans[i] = 0;

		}
		
		int now = 1;

		for(int i = 2; i <= n; i++) {
			
			System.out.print("? " + now + " " + i);

			System.out.println();

			int tmp1 = sc.nextInt();

			System.out.print("? " + i + " " + now);
			
			System.out.println();

			int tmp2 = sc.nextInt();
				
			if(tmp1 < tmp2) {
				
				vis[tmp2] = 1;

				ans[i] = tmp2;

			} 
			
			else {
				
				ans[now] = tmp1;
				
				vis[tmp2] = 1;

				now = i;
				
			}			

		}

		for(int i = 1; i <= n; i++) {
			
			if(vis[i] == 1) continue;

			ans[now] = i;

		}
		
		System.out.print("! ");

		for(int i = 1; i <= n; i++) {

			System.out.print(ans[i] + " ");

		}

	}
