# 2849. Determine if a Cell Is Reachable at a Given Time
給定起點跟終點,是否能在時間內從起點到終點,移動方式是周圍8格,一秒一步
```python
class Solution:
def isReachableAtTime(self, sx: int, sy: int, fx: int, fy: int, t: int) -> bool:
width = abs(sx - fx)
height = abs(sy - fy)
if width == 0 and height == 0 and t == 1:
return False
return t >= max(width, height)
```
