`#3793` cort

O curte dreptunghiulară de lungime N și lățime M (vom numi N linii și M coloane) este pavată cu dale
pătrate de dimensiune 1. Dalele au două culori, sunt albe sau negre (vom codifica dalele albe cu 0 și dalele negre cu 1). Dalele negre sunt fabricate dintr-un material mult mai rezistent decât dalele albe, iar Ionel ar vrea sa monteze un cort de suprafață maximă sub care să fie doar dale negre. El știe de asemenea că există doar corturi dreptunghiulare și pătrate, de orice dimensiune. Din motive tehnice, Ionel poate să facă doar următoarele operații cu dalele din curte:
să schimbe între ele oricâte dale de pe aceeși linie;
să schimbe de oricâte ori dorește o linie întreagă cu altă linie tot întreagă;
Scrieți un program care rezolvă următoarele două cerințe:
1. Afișează numărul maxim de dale negre care s-ar putea obține pe o coloană după rearanjare;
2. Afișează aria maximă a cortului ce poate fi amplasat doar pe dale negre.

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 cort 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.
