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()))

for comb in itertools.combinations(num, 2):
    diff = abs(comb[0] - comb[1])
    if diff % (n-1) == 0:
        print(comb[0], comb[1])
        break
