本问题改编自 Wolfram Challenges 网站Count the Number of Squares ,因此您可能需要先查看该页面,了解本问题的可视化说明。

给定一个点序列(坐标x, y 为非负整数),您的函数应该计算有多少个正方形的四个角都是点。请注意,这些正方形不需要轴对齐,因此它们的边必须是水平和垂直的。例如,点 (0, 3), (3, 0), (6, 3), (3, 6)定义了一个正方形,即使从轴线对齐的角度看它可能恰好是一个菱形。

顺便说一句,如果你想尝试另一种方法,用点与点之间的线来计算正方形,The Square Chest 等着你!

CheckiO Extensions

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

checkio sync

(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
checkio install-plugin --ff
checkio install-plugin --chromium

Read more here about other functionality that the checkio client provides. Feel free to submit an issue in case of any difficulties.
