for a in range(4):
    for b in range(min(4,7 - a + 1,a + 1)):
        c = 7 -a -b
        if c >= 4 or c > b: 
            continue
        ah = int((3.5 - a) / 0.5)
        bh = int((3.5 - b) / 0.5)
        ch = int((3.5 - c) / 0.5)
        if ah + bh + ch == 7:
            print("*" * 18)
            print(a, ah, 7 - a - ah)
            print(b, bh, 7 - b - bh)
            print(c, ch, 7 - c - ch)
