Hello Here are some clarifications regarding the wording of the assignment texts: The phrase "Do not use packages! We do not need them." only refers to your code. It it somewhat trickier for me to compile your code when it is placed in packages, so please, do not use that feature. The packages in the standard library should of course be used when appropriate. The requirement for the B and A grades in assignment 1 includes that the output stays sorted even if the keys in the property map are changed or added to. -fk
