This is the solution I came up with for the Codingame hackaton: The Accountant. Codingame is a creat way to combine programming and gaming. I ended 5th of the 73 belgian people. Hackaton description: For this mission, you take the role of Christian Wolff, an unconventional accountant who has lived as a double agent for years. He has gathered highly sensitive data while working for the most dangerous criminal organizations of the world. As things are starting to unravel, it is expected that Wolff’s enemies will attempt to get their hands on these files. As Wolff cannot risk to blow his cover up, we need you to make sure the data is secure.
