Problem Breakdown

Understanding the Erect the Fence Problem

Let's break down this LeetCode problem and understand what makes it challenging in interview settings.

Problem Statement

You are given an array trees where trees[i] = [xi, yi] represents the location of a tree in the garden. 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. You may return the answer in any order.

INPUT
trees = [[1,1],[2,2],[2,0],[2,4],[3,3],[4,2]]
OUTPUT
[[1,1],[2,0],[4,2],[3,3],[2,4]]
EXPLANATION

All the trees will be on the perimeter of the fence except the tree at [2, 2], which will be inside the fence.

Example 2
INPUT
trees = [[1,2],[2,2],[4,2]]
OUTPUT
[[4,2],[2,2],[1,2]]
EXPLANATION

The fence forms a line that passes through all the trees.

Constraints

1 <= trees.length <= 3000
trees[i].length == 2
0 <= xi, yi <= 100
All the given positions are unique.
