#2251
Localitatea Târgovişte este în plină modernizare. Primăria decide să inventarieze toate clădirile din oraş pentru a renova faţadele acestora. În acest sens analizează harta oraşului şi constată că toţi pereţii sunt aşezaţi doar pe direcţia Nord Sud sau Est Vest. Pereţii vizibili de către turiști sunt doar aceia la care se poate ajunge din exteriorul orașului prin deplasarea pe cele două direcţii date, în oricare din cele patru sensuri (N, E, S, V). Harta oraşului este întocmită pe un caroiaj format din pătrate cu latura 1. Cunoscându-se harta oraşului, determinaţi lungimea pereţilor vizibili ce urmează a fi zugrăviţi.

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 Pereti 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.
