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.

Solution (in CPP):

Solution:
#include <bits/stdc++.h>
using namespace std;
inline int query(int i, int j) {
  cout << "? " << i + 1 << ' ' << j + 1 << endl;
  int now;
  cin >> now;
  return now;
}
signed main() {
  ios::sync_with_stdio(false);
  cin.tie(nullptr), cout.tie(nullptr);
  int n;
  cin >> n;
  vector<int> p(n);
  vector<int> inds(n);
  iota(inds.begin(), inds.end(), 0);
  while (inds.size() > 1) {
    int i = inds.back();
    inds.pop_back();
    int j = inds.back();
    inds.pop_back();
    int x = query(i, j);
    int y = query(j, i);
    if (x < y) {
      swap(x, y);
      swap(i, j);
    }
    p[i] = x;
    inds.push_back(j);
  }
  vector<char> used(n + 1, 0);
  for (auto x : p) used[x] = 1;
  int free = 1;
  while (free < n && used[free]) free++;
  p[inds[0]] = free;
  cout << "! ";
  for (auto x : p) cout << x << ' ';
  cout << '\n';
