果然是这样的,是不是有的点故意把某个角色给卡死角了,然后一直遇不到啊?
这里投机取巧了一下然后就AC了
```python
def cal_time():
del_time = 0
next_dir_cow = [0]
next_dir_John = [0]
while cow_pos != John_pos:
each_move(John_pos, next_dir_John, "F")
each_move(cow_pos, next_dir_cow, "C")
del_time += 1
if del_time > 1000:
# 超过1000直接返回None默认不相遇
return None
return del_time
```
虽然思路不正确,但是还是过掉了
