The Hamming distance between two binary integers is the number of bit positions that differs (read more about the Hamming distance on Wikipedia). For example:
117 = 0 1 1 1 0 1 0 1 17 = 0 0 0 1 0 0 0 1 H = 0+1+1+0+0+1+0+0 = 3
You are given two positive numbers (N, M) in decimal form. You should calculate the Hamming distance between these two numbers in binary form.
Input: Two arguments as integers.
Output: The Hamming distance as an integer.
hammingDistance(117, 17) == 3 hammingDistance(1, 2) == 2 hammingDistance(16, 15) == 5
How it is used: This is a basis for Hamming code and other linear error-correcting programs. The Hamming distance is used in systematics as a measure of genetic distance. On a grid (ie: a chessboard,) the Hamming distance is the minimum number of moves it would take a rook to move from one cell to the other.

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=js 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
