+
+
+## 题目:
+
+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:**
+
+1. Both rectangles `rec1` and `rec2` are lists of 4 integers.
+2. All coordinates in rectangles will be between `-10^9` and `10^9`.
+
+
+## 题目大意
+
+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：
+
+1. 两个矩形 rec1 和 rec2 都以含有四个整数的列表的形式给出。
+2. 矩形中的所有坐标都处于 -10^9 和 10^9 之间。
+
+
+## 解题思路
+
+- 给出两个矩形的坐标，判断两个矩形是否重叠。
+- 几何题，按照几何方法判断即可。
