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