Lui Alexandru îi place sa circule cu autobuzul, deși câteodată poate să fie prea aglomerat. Ajutați-l pe Alexandru să afle niște statistici despre autobuzul său favorit. Urmărind traseul autobuzului și cunoscând câte persoane urcă și coboară la fiecare stație, să se afle:
a) Numărul total de persoane care au urcat în autobuz, numărul total de persoane care au coborât din autobuz și numărul de persoane aflate în autobuz după terminarea traseului.
b) Știind că Alexandru se află la stația cu numărul de ordin x, să se afle dacă autobuzul în care urmează să urce este aglomerat. Un autobuz este considerat aglomerat dacă în el se află cel puțin y persoane înainte să ajungă în stație.

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 RATC 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.
