SumTri_XI

#3259

Se consideră un triunghi de numere întregi 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, în funcție de modul de parcurgere a numerelor din triunghi. Unul dintre aceste moduri este următorul:

• se pleacă din ultimul element al ultimei linii
• se merge întotdeauna spre stânga pe aceeași linie sau pe linia de deasupra, adică de pe linia i și coloana j se merge pe linia i și coloana j-1 sau pe linia i-1 și coloana j-1.
• parcurgerile se termină pe prima coloană.

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