Please listen up!
I need assistance with preparation for coding session
The CodeSignal screen is meant to test general coding ability. 
I’ll be asked to implement a simple coding project from a spec and develop it to the point that it passes some tests. 
I should prioritize 
a) writing code that passes as many tests as possible and 
b) progressing through all four levels quickly. 
It'll essentially be a toy simulation of an app that won't require anything except the standard library of chosen programming language. 
Note there's no framework/UI or anything similar — basically, it's like the core business logic of an app, but nothing else. 
It won’t test detailed knowledge of algorithms, compute systems, or machine learning.
