Answer 1

def read_matrix():
    n = int(input())


    M = []
    for i in range(n):
        line = input()
        row = [int(s) for s in line.split()]
        M.append(row)

    return M


def antidiagonal(M):
    n = len(M)
    L = []
    for i in range(n):
        x = M[i][n-1-i]
        L.append(x)
    return L


def main():
    M = read_matrix()
    D = antidiagonal(M)
    for x in D:
        print(x, end=' ')
 

main()
