`#2676` afise

Campania electorală s-a terminat de mult, dar zidul din parcul central al oraşului în care au fost puse afişele este încă într-o formă dezolantă. Ploile şi vântul au acţionat şi au urâţit şi mai mult această zonă pe care altă dată erau afişe frumos colorate. Primăria a decis să se ocupe de această problemă. A format o comisie şi a decis realizarea unor panouri reclamă care să ascundă porţiunile deteriorate. Deoarece fondurile sunt mici s-a decis să fie alocate doar un anumit număr de panouri publicitare care trebuie să ocupe o suprafaţă cât mai mică posibil. Comisia a primit datele din teren sub forma: lungime zid, câte unităţi sunt ocupate cu afişe ce trebuie acoperite şi care este numărul de panouri pe care le poate folosi. De asemenea se primesc ca date şi care sunt unităţile de zid ocupate cu afişe deja deteriorate.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

probleme la care rezolvarea presupune scrierea unui program complet
probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema afise face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
