#385
SumTri
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:
i
al sumei se află pe linia i
din triunghiSă se determine cea mai mare sumă care se poate obține în acest mod.
