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**.
