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

2
1 2


Output

1 4
5 4


Input

3
3 2 1


Output

1 2 3
5 3 1


Input

3
2 3 1


Output

5 10 100
100 10 1

Solution (in PYTHON3):

Solution:
def main():
    N = int(input())
    P = list(map(int, input().split()))
    delta = [0] * N
    for i, p in enumerate(P):
        delta[p-1] = i
    A = [0] * N
    B = [0] * N
    A[0] = a = delta[0] + 1
    B[0] = b = int(1e9)

    for i in range(1, N):
        a += 1
        b -= 1
        tmp = delta[i] - delta[i-1]
        if tmp > 0:
            a += tmp
        else:
            b += tmp
        A[i] = a
        B[i] = b
    print(*A)
    print(*B)
