#4220 Alimentarea mașinii

Vrei să călătorești n kilometri din orașul A în orașul B cu o mașină care are un rezervor de combustibil care poate asigura un număr de m kilometri. Între cele două orașe sunt amplasate stații de alimentare cu combustibil. Mașina pleacă din orașul A cu rezervorul plin. Vrei să știi numărul minim de alimentări necesare parcurgerii distanței între cele două orașe sau dacă nu se poate parcurge distanța din cauza alimentării (ai o mașină electrică și nu prea sunt stații electrice de alimentare :) )

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 Alimentarea mașinii 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.
