#3739 cafea

Algorel a primit de la părinţi o sumă de bani, S, şi o plasă în care încap K grame de cafea. Algorel trebuie să meargă la piaţă şi să cumpere suficientă cafea încât să umple plasa. Pe de altă parte, părinţii nu îi cer înapoi restul. Dacă va reuşi să umple plasa, va putea păstra diferenţa de bani dintre suma primită S şi costul total al cafelei achiziţionate. Dacă nu va reuşi să umple plasa, atunci nu va rămâne cu niciun ban. Ajutaţi-l pe Algorel să rămână cu o sumă cât mai mare de bani, scriind un program care face acest calcul pe baza datelor corespunzătoare comercianţilor.

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 cafea 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.
