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.矩形以列表 [x1, y1, x2, y2] 的形式表示,其中 (x1, y1) 为左下角的坐标,(x2, y2) 是右上角的坐标。如果相交的面积为正,则称两矩形重叠。需要明确的是,只在角或边接触的两个矩形不构成重叠。给出两个矩形,判断它们是否重叠并返回结果。
说明:
package leetcode
func isRectangleOverlap(rec1 []int, rec2 []int) bool {
return rec1[0] < rec2[2] && rec2[0] < rec1[2] && rec1[1] < rec2[3] && rec2[1] < rec1[3]
}
