Erect the Fence
Explore how to enclose a set of points using the shortest possible fence, forming the convex hull. Learn to identify trees on the fence perimeter by applying geometric problem-solving techniques. Practice implementing a solution to efficiently determine boundary points for coding interviews.
We'll cover the following...
Statement
You are given an array of points, trees, where trees[i] = [xᵢ, yᵢ] represents the location of a tree on a 2D plane. Your goal is to enclose all the trees using the shortest possible length of rope, forming a fence around the garden. A garden is considered well-fenced if every tree lies inside or on the boundary of the fence (i.e., the fence forms the
Return the coordinates of the trees that lie exactly on the fence perimeter. You can return the answer in any order.
