Sindbad a descoperit un recipient care conține o poțiune magică și o inscripție care descrie cum se poate deschide poarta unui templu. Urmând instrucțiunile din inscripție, Sindbad a ajuns la un tunel acoperit cu dale pătrate, aliniate astfel încât formează linii și coloane. Tunelul are mai multe linii, iar pe fiecare linie sunt câte N dale. Dalele din tunel sunt numerotate începând cu 1, astfel încât, parcurgându-le linie cu linie și fiecare linie de la stânga la dreapta, se obține un șir strict crescător de numere naturale consecutive.
Sindbad se află la intrare, înaintea primei linii. Pentru a deschide poarta templului, el trebuie să ajungă pe dala numerotată cu P, călcând pe un număr minim de dale. Dacă există mai multe astfel de soluții, o va alege pe cea pentru care consumul total de picături de poțiune magică este minim.

Scrieți un program care citește valorile N și P și rezolvă următoarele cerințe:
1. afișează numărul minim de dale pe care trebuie să calce pentru a deschide poarta;
2. afișează numărul natural T, reprezentând numărul minim de picături de poțiune magică necesare pentru deschiderea porții.

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 poarta1 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.

Du-te sus!
