#1856 Taxe2

Într-o ţară în care corupţia este în floare şi economia la pământ, pentru a obţine toate aprobările necesare în scopul demarării unei afaceri, investitorul trebuie să treacă prin mai multe camere ale unei clădiri în care se află birouri.

Clădirea are un singur nivel în care birourile sunt lipite unele de altele formând un caroiaj pătrat de dimensiune n•n. Pentru a facilita accesul în birouri, toate camerele vecine au uşi între ele. În fiecare birou se află un funcţionar care pretinde o taxă de trecere prin cameră (taxă ce poate fi, pentru unele camere, egală cu 0). Investitorul intră încrezător prin colţul din stânga-sus al clădirii (cum se vede de sus planul clădirii) şi doreşte să ajungă în colţul opus al clădirii, unde este ieşirea, plătind o taxă totală cât mai mică.

Ştiind că el are în buzunar S euro şi că fiecare funcţionar îi ia taxa de cum intră în birou, se cere să se determine dacă el poate primi aprobările necesare şi, în caz afirmativ, care este suma maximă de bani care îi rămâne în buzunar la ieşirea din clădire.

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 Taxe2 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.
