# Leetcode 836 - Rectangle Overlap

`Note:`

- Project both rectangles to
`x-axios`

and`y-axios`

. - It’s easier to get when they don’t overlap.
- Reverse the bool.

`Question:`

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] |

`Code:`
