Se consideră o matrice pătratică cu n linii şi n coloane şi elemente numere naturale distincte. Cele două diagonale delimitează în matrice 4 zone:
NORD– elementele situate deasupra diagonalei principale şi deasupra celei secundareEST– elementele situate deasupra diagonalei principale şi sub cea secundarăSUD– elementele situate sub diagonala principală şi sub cea secundarăVEST– elementele situate sub diagonala principală şi deasupra celei secundare
Să se modifice matricea în felul următor: se determină cele 4 maxime din zonele determinate de cele două diagonale și se interschimbă maximele în sensul acelor de ceas.
Mai exact, elementul maxim din zona nord va ajunge în locul elementului maxim din zona de est, cel din zona de est în locul celui din zona de sud, cel din zona de sud în cea de vest, iar cel din zona de vest în cea de nord.

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 Matrice19 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.
