Un număr de postere dreptunghiulare, fotografii și alte imagini de aceeași formă sunt lipite pe un perete. Laturile lor sunt toate verticale sau orizontale. Fiecare dreptunghi poate fi parțial sau total acoperit de celelalte. Lungimea limitei unirii tuturor dreptunghiurilor se numește perimetru. Scrieți un program care calculează perimetrul.
