Problem: You are given a permutation p of the set {1, 2, ..., N}. Please construct two sequences of positive integers a_1, a_2, ..., a_N and b_1, b_2, ..., b_N satisfying the following conditions:

* 1 \leq a_i, b_i \leq 10^9 for all i
* a_1 < a_2 < ... < a_N
* b_1 > b_2 > ... > b_N
* a_{p_1}+b_{p_1} < a_{p_2}+b_{p_2} < ... < a_{p_N}+b_{p_N}

Constraints

* 2 \leq N \leq 20,000
* p is a permutation of the set {1, 2, ..., N}

Input

The input is given from Standard Input in the following format:


N
p_1 p_2 ... p_N


Output

The output consists of two lines. The first line contains a_1, a_2, ..., a_N seperated by a space. The second line contains b_1, b_2, ..., b_N seperated by a space.

It can be shown that there always exists a solution for any input satisfying the constraints.

Examples

Input

3 2 1


Output

1 2 3
5 3 1


Input

3
2 3 1


Output

5 10 100
100 10 1

Solution:
import java.util.*;
public class Main{
  public static void main(String[] args){
    Scanner sc = new Scanner(System.in);
    int n = sc.nextInt();
    int[] p = new int[n];
    for(int i=0;i<n;i++)p[i]=sc.nextInt();
    int[] a = new int[n];
    int[] b = new int[n];
    int[] r = new int[n];
    for(int i=0;i<n;i++)r[p[i]-1]=i;
    for(int i=0;i<n;i++){
      a[i]=30000*(i+1);
      b[i]=30000*(n-i)+r[i];
    }
    System.out.print(a[0]);
    for(int i=1;i<n;i++)System.out.print(" "+a[i]);
    System.out.println("");
    System.out.print(b[0]);
    for(int i=1;i<n;i++)System.out.print(" "+b[i]);
    System.out.println("");
  }
