n1 = int(input())
n2 = int(input())
n3 = int(input())

for i in range(1, n1 + 1):
    for x in range(1, n2 + 1):
        for z in range(1, n3 + 1):
            if i % 2 == 0:
                if z % 2 == 0:
                    if x == 2 or x == 3 or x == 5 or x == 7:
                        print(f"{i} {x} {z}")
