篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了[LeetCode] 850. Rectangle Area II 矩形面积之二相关的知识,希望对你有一定的参考价值。
We are given a list of (axis-aligned)?rectangles
.? Each?rectangle[i] = [x1, y1, x2, y2]?
, where (x1, y1) are the coordinates of the bottom-left corner, and (x2, y2) are the coordinates of the top-right corner of the?i
th rectangle.
Find the total area covered by all?rectangles
?in the plane.? Since the answer?may be too large,?return it modulo 10^9 + 7.
Example 1:
Input: [[0,0,2,2],[1,0,2,3],[1,0,3,1]]
Output: 6
Explanation: As illustrated in the picture.
Example 2:
Input: [[0,0,1000000000,1000000000]]
Output: 49
Explanation: The answer is 10^18 modulo (10^9 + 7), which is (10^9)^2 = (-7)^2 = 49.
Note:
1 <= rectangles.length <= 200
rectanges[i].length = 4
0 <= rectangles[i][j] <= 10^9
- The total area covered by all rectangles will never exceed?
2^63 - 1
?and thus will fit in a 64-bit signed integer.
