Introduction
When dealing with data in two dimensions, data scientists looove to see straight lines emerge, as they can use a simple linear regression to model it - meaning we assume it is in the form of y=mx+b, and all that's left is to find the best m and b to describe the data.
There are sev...

Conversion
Assume that there is a number a. In every conversion of that number, the number can either convert itself to its value plus the value of one of its digits, or convert itself to its value minus the value of one of its digits.
In this situation, find the minimum number of conversions o...
Let's say I have a grid of pixels as follows:
-----------***--
-----------*****
---**********---
--*-********----
-*--*-*--*-*----
I can choose any point on this image using coordinates: e.g grid[0][1] (0-indexed) = (1, 2) (1-indexed) = {x=1, y=2} = -.
I can also choose a square on this grid,...
An analog clock has 2 hands*: Hour and minute.
These hands circle the clock's face as time goes by. Each full rotation of the minute hand results in 1/12th of a rotation of the hour hand. 2 full rotations of the hour hand signifies a full day.
As these hands are fixed to the same central point, ...
