Extracted text: 3. Use proper abstract list processing functions to do following task: consumes a list of intern structure as its parameter and produces list of number which represents how many date/s each intern works. Example: Contract for abstract functions for list-processing: filter: [X - Boolean] [List-of X] - [List-of X] map: [X - Y] [List-of X] → [List-of Y] foldr/foldl: [X Y → Y] Y [List-of X] → Y
