Understanding the Rectangle Area I I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
You are given a 2D array of axis-aligned rectangles. Each rectangle[i] = [xi1, yi1, xi2, yi2] denotes the ith rectangle where (xi1, yi1) are the coordinates of the bottom-left corner, and (xi2, yi2) are the coordinates of the top-right corner. Calculate the total area covered by all rectangles in the plane. Any area covered by two or more rectangles should only be counted once. Return the total area. Since the answer may be too large, return it modulo 109 + 7.

Examples
rectangles = [[0,0,2,2],[1,0,2,3],[1,0,3,1]]6A total area of 6 is covered by all three rectangles, as illustrated in the picture. From (1,1) to (2,2), the green and red rectangles overlap. From (1,0) to (2,3), all three rectangles overlap.
rectangles = [[0,0,1000000000,1000000000]]49The answer is 1018 modulo (109 + 7), which is 49.
Constraints
1 <= rectangles.length <= 200rectanges[i].length == 40 <= xi1, yi1, xi2, yi2 <= 109xi1 <= xi2yi1 <= yi2All rectangles have non zero area.How Interview Coder Helps with Leetcode Problems
