两个计数器挤在一起

运行下面这段程序，填写它打印出来的结果。

BLK = 4

def traffic(seq):
    owner = {}
    moves = 0
    for core, addr in seq:
        b = addr // BLK
        if owner.get(b, -1) != core:
            moves = moves + 1
            owner[b] = core
    return moves

seq = []
for _ in range(5):
    seq.append((0, 0))
    seq.append((1, 1))
print(str(len(seq)) + "/" + str(traffic(seq)))
