    836 - Rectangle Overlap.

    Easy

    An axis-aligned rectangle is represented as a list [x1, y1, x2, y2], where (x1, y1) is the coordinate of its bottom-left corner, and (x2, y2) is the coordinate of its top-right corner. Its top and bottom edges are parallel to the X-axis, and its left and right edges are parallel to the Y-axis.

    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 rec1 and rec2, return true if they overlap, otherwise return false.

    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

    Example 3:

    Input: rec1 = [0,0,1,1], rec2 = [2,2,3,3]

    Output: false

    Constraints:

    • rect1.length == 4
    • rect2.length == 4
    • -109 <= rec1[i], rec2[i] <= 109
    • rec1 and rec2 represent a valid rectangle with a non-zero area.
