587 - Erect the Fence\.
Hard
You are given an array `trees` where
trees[i] = [xi, yi] represents the location of a tree in the garden.
You are asked to fence the entire garden using the minimum length of rope as it is expensive. The garden is well fenced only if **all the trees are enclosed**.
Return _the coordinates of trees that are exactly located on the fence perimeter_.
**Example 1:**

**Input:** points = \[\[1,1],[2,2],[2,0],[2,4],[3,3],[4,2]]
**Output:** [[1,1],[2,0],[3,3],[2,4],[4,2]]
**Example 2:**

**Input:** points = \[\[1,2],[2,2],[4,2]]
**Output:** [[4,2],[2,2],[1,2]]
**Constraints:**
* `1 <= points.length <= 3000`
* `points[i].length == 2`
* 0 <= xi, yi <= 100
* All the given points are **unique**.-
