Structure

• Main.java: in this file you can find the main, that calls the days code. to call the right code, you need to add the right number here:

  Days day = new DayX(reader.readInput("test.txt"));//exchange X for the number of the day

• days: the code for each day will be in the days folder as a .java file. I used Days.java to create an Interface, that I then could implement every day to be faster in writing the code for every day.
• Inputs: all my input data for each day is saved the inputs folder as a .txt file. I also have a test.txt file, that I use for the example input of each days puzzle.
• Reader.java: This class helps to read the input data.
