#4112
Pe teritoriul insulelelor FalkLand exista n britanici notati de la 1 la n si m argentinieni notati de la 1 la m.
Se știe că fiecare britanic poate lega o singura relație de prietenie cu una dintre cunoștințele sale Argentiniene și vice-versa. Pentru a detensiona relațiile, cele două naționalități sunt obligate să se cunoască și să lege cât mai multe relații de prietenie.
Având în vedere faptul că fiecare britanic poate lega o singură relație de prietenie cu un argentinian, iar relatiie de prietenie se știu deoarece acestea sunt evidente, Margaret Thatcher va solicită ajutorul în aflarea numărului maxim de relații noi de prietenie care se vor lega pe insula .

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 Falkland 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.
