`#4661` dominoes

Se dă o matrice cu 2 linii si n coloane care are k celule ocupate. Se dau q interogări de forma (x1, y1, x2, y2), cu următoarea semnificație: dacă se ocupă două celule libere distincte ale matricii inițiale, (x1, y1) și (x2, y2), se poate pava complet matricea cu piese de domino de dimensiuni 2 x 1 și 1 x 2? După efectuarea unei interogări celulele ocupate asociate acesteia vor deveni din nou libere (modificările aduse matricei nu persistă între interogări). Să se determine, pentru fiecare interogare, dacă este posibil ca matricea să fie pavată complet cu piese de domino de dimensiuni 2 x 1 și 1 x 2.

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 dominoes 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.
