#3321
Peste 3700 de ani lumea a devenit dreptunghiulară, este formată n x m zone și este stăpânită de un rege care are o armată formată din q soldați. În regat se află k turnuri de piatră, ostile armatei regelui, la coordonate cunoscute; fiecare turn atacă zonele de pe linia și coloana sa.
Regele dorește să afle în câte moduri poate plasa soldații în zonele fără turnuri ale regatului astfel încât aceștia să nu fie atacați de turnuri.

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 Stone 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.
