A rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) are the coordinates of its bottom-left corner, and (x2, y2) are the coordinates of its top-right corner.
Two rectangles overlap if the area of their intersection is positive. To be clear, two rectangles that only touch at the corner or edges do not overlap.
Given two (axis-aligned) rectangles, return whether they overlap.
Example 1:
Input: rec1 = [0,0,2,2], rec2 = [1,1,3,3] Output: true
Example 2:
Input: rec1 = [0,0,1,1], rec2 = [1,0,2,1] Output: false
Notes:
rec1 and rec2 are lists of 4 integers.-10^9 and 10^9.解法1：
class Solution(object):
def isRectangleOverlap(self, rec1, rec2):
"""
:type rec1: List[int]
:type rec2: List[int]
:rtype: bool
"""
return not (rec1[1] >= rec2[3] # higher
or rec1[3] <= rec2[1] # lower
or rec1[2] <= rec2[0] # lefter
or rec1[0] >= rec2[2]) # righter
解法2：
class Solution:
def isRectangleOverlap(self, rec1, rec2):
"""
:type rec1: List[int]
:type rec2: List[int]
:rtype: bool
"""
x_overlap = min(rec1[2], rec2[2]) - max(rec1[0], rec2[0])
y_overlap = min(rec1[3], rec2[3]) - max(rec1[1], rec2[1])
return x_overlap > 0 and y_overlap > 0
