Interesting, intersecting

A square on the two-dimensional plane can be defined as a tuple (x, y, l), where (x, y) are the coordinates of its bottom left corner and l is the length of the side of the square (we only consider squares that are aligned to the axes). Given two squares as tuples (x1, y1, l1) and (x2, y2, l2), your function should determine whether these two squares intersect, that is, their areas have at least one point in common, even if that one point is merely the shared corner point when these two squares are placed kitty corner.

We also prepared a stick and a carrot for you:

  • try to write this mission with no loops or list comprehensions of any kind, but should compute the result using only integer comparisons and conditional statements;

  • it is actually much easier to determine that the two squares do not intersect, and then negate that answer. Two squares do not intersect if one of them ends in the horizontal direction before the other one begins, or if the same thing happens in the vertical direction.

Input: Two tuples with three integers in each.

Output: Bool.

Examples:

assert squares_intersect((2, 2, 3), (5, 5, 2)) == True
assert squares_intersect((3, 6, 1), (8, 3, 5)) == False
assert squares_intersect((3000, 6000, 1000), (8000, 3000, 5000)) == False

This task is taken from the course CCPS 109 Computer Science I, as taught by Ilkka Kokkarinen.

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.
