A venit ora mesei pentru Por Costel (masa dintre prânz și cină). Scormonind printr-o grădină, el descoperă un număr de N coceni de porumb și M mere. Masa lui Por Costel va consta în exact un cocean și un măr. Însă, mai nou, fanii săi l-au atenționat că trebuie să aibă grijă ce mănâncă. Fiecare cocean și fiecare măr are o valoare nutritivă. Valoarea nutritivă a mesei va fi valoarea nutritivă a coceanului ales + valoarea nutritiva a mărului ales. Dându-se valorile nutritive ale cocenilor și ale merelor, Por Costel vă întreabă dacă există o masă pe care o poate lua cu valoare nutritivă X. Pentru că Por Costel vrea sa mănânce de mai multe ori între prânz și cină, el va vă pune T întrebări de forma aceasta.
(Întrebările sunt independente între ele, a nu se considera că după o întrebare se elimină perechea cocean-mar aleasă).

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 gustare 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.
