The problem
You are given a 2D integer array trees where trees[i] = [xi, yi] represents the location of the ith tree in the garden. You are asked to fence the entire garden using the minimum length of rope possible.
Example
- Input
- trees = [[1,1],[2,2],[2,0],[2,4],[3,3],[4,2]]
- Output
- [2.00000,2.00000,2.00000]
- Explanation
- The fence will have center = (2, 2) and radius = 2
