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
def solve():
    n = int(input())
    li = [int(_) for _ in input().split()]
    for i in range(n):
        for j in range(i+1, n):
            if abs(li[i]-li[j]) % (n-1) == 0:
                print(str(li[i]) + " " + str(li[j]))
                return

solve()
