problem

Given $ N $ different natural numbers $ a_i $. I decided to make a pair by choosing a different natural number from the given natural numbers. Output one pair that can be created with a value difference that is a multiple of $ N -1 $.

It should be noted that such a pair always exists.





Example

Input

5
1 2 4 7 10


Output

2 10
import itertools
N = int(input())

num = list(map(int, input().split()))


a = itertools.combinations(num, 2)

for i, j in a:
    if abs(i - j) % (N-1) == 0:
        print(i , j)
        break
