Dodel
Dodel manelistul a fost surprins de către domnul profesor de informatică în timp ce asculta manele la căști în timpul orei de informatică. Domnul profesor îi dă să rezolve o problemă de informatică, iar dacă nu reușește până la finalul orei, Dodel va fi pedepsit să asculte muzică rock până la finalul anului școlar. Disperat de această perspectivă sumbră, Dodel vă roagă sa îl ajutați să rezolve problema de informatică primită.
Se dă o matrice cu n linii şi n coloane şi elemente numere întregi. Calculaţi cel mai mare produs care se poate obține prin înmulțirea unui element de pe diagonala principală cu unul de pe diagonala secundară.

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 Dodel 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.
