The recurrence of 10198
Hy Dmytro_Chernysh, I would like to know if you got Accepted using this recurence: f[1]:=2; f[2]:=5; f[3]:=13; f[n]:=2*f[n-1]+f[n-2]+f[n-3]. I'm asking because I tried do use it, but I got WA. Maybe, I am having problems like ravingavin. The numbers became very big and their representation can be do...
