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
n = int(input())
a = list(map(int, input().split()))
a.sort()
for i in a:
    for j in a:
        if abs(i-j)%(n-1) == 0 and i != j:
            print(i, j)
            quit()
