You are given a list of points on a coordinate plane. We need you find the convex hull formed by these points. The convex hull of a set X of points in the Euclidean plane is the smallest convex set that contains X. For instance: when X is a bounded subset of the plane, the convex hull may be visualized as the shape formed by a rubber band stretched around X. If a point lies on edge, it's included.
The points are presented as a list of coordinates [x, y] in which x and y are integers. The result returns as a sequence of indexes of points in the given list; points lie on the convex hull in clockwise order (see the picture). The sequence starts from the bottom...

CheckiO Extensions allow you to use local files to solve missions. More info in a blog post.
In order to install CheckiO client you'll need installed Python (version at least 3.8)
Install CheckiO Client first:
pip3 install checkio_client
Configure your tool
checkio --domain=py config --key=
Sync solutions into your local folder
(in beta testing) Launch local server so your browser can use it and sync solution between local file end extension on the fly. (doesn't work for safari)
checkio serv -d
Alternatevly, you can install Chrome extension or FF addon
checkio install-plugin --ff
checkio install-plugin --chromium
