Read the exercise instructions completely before you start
implementing a solution. Analyze the requirements and then come up with a
program layout of scripts and functions. What would be a
suitable function to solve the core task? Which arguments should it
take? Which results should it return?

One function that computes one realisation of a random walk.
Scripts for plotting and analysis.
