836. Rectangle Overlap

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。

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

Note

• Both rectangles rec1 and rec2 are lists of 4 integers.
• All coordinates in rectangles will be between -10^9 and 10^9.

Solution

• JavaScript Solution

/**
 * @param {number[]} rec1
 * @param {number[]} rec2
 * @return {boolean}
 */
var isRectangleOverlap = function(rec1, rec2) {
    if (rec2[0] >= rec1[2] || rec2[1] >= rec1[3] || rec1[0] >= rec2[2] || rec1[1] >= rec2[3]) {
        return false;
    }
    return true;
};
