SumTri

#385

Se consideră un triunghi de numere naturale format din n linii.Prima linie conține un număr, a doua linie conține 2 numere, etc. ultima linie n, conține n numere. În acest triunghi se pot calcula diverse sume cu n elemente, astfel:

termenul i al sumei se află pe linia i din triunghi
pentru un anumit termen al sumei, termenul următor se află pe linia următoare și pe aceeași coloană, sau pe coloana imediat următoare spre dreapta.

Să se determine cea mai mare sumă care se poate obține în acest mod.

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 SumTri 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!
