#550 Mere

Țăranul Ion are în livada sa N pomi, fiecare cu v[i] mere. Între pomi există N-1 cărări, astfel încât între oricare doi pomi să existe un singur drum, alcătuit eventual din mai multe cărări. Pentru că nu și-a plătit ratele la bancă, el este nevoit să vândă o parte dintre pomi. El vrea să adune merele din livadă, dar pentru că nu are foarte mult timp, el va aduna merele doar dintr-o parte din pomi.

Ion pornește din pomul lui preferat, pomul 1, și se deplasează spre unul din vecinii lui. Pentru că nu este foarte inteligent, atunci când Ion se află la un pom, el se va deplasa către pomul vecin care are cele mai multe mere, fără să ia în calcul ceilalți meri din livadă. Dacă doi pomi au același număr de mere, atunci Ion se va deplasa spre pomul cu numărul de ordine mai mic.

Ajutați-l pe Ion să afle câte mere va aduna folosind metoda sa!

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 Mere 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.
