leetcode-5361-圆和矩形是否有重叠

Posted 2020-11-27 真不知道叫啥好

题目描述：

 

 

class Solution:
    def checkOverlap(self, radius: int, x_center: int, y_center: int, x1: int, y1: int, x2: int, y2: int) -> bool:
        a = max(0, x1 - x_center, x_center - x2) ** 2 
        b = max(0, y1 - y_center, y_center - y2) ** 2
        c = radius ** 2
        return a + b <= c

class Solution:
    def checkOverlap(self, radius: int, x_center: int, y_center: int, x1: int, y1: int, x2: int, y2: int) -> bool:
        for x in (x1, x2):
            for y in (y1, y2):
                if dist((x_center, y_center), (x, y)) <= radius:
                    return True
        if x1 <= x_center <= x2 and y1 - radius  <= y_center <= y2 + radius:
            return True
        if x1 - radius <= x_center <= x2 + radius and y1  <= y_center <= y2:
            return True
        return False
