Ghiocel2

#4958

Într-un oraș sunt n case numerotate de la 1 la n. Între anumite case sunt străzi bidirecționale. În casa cu numărul g locuiește Ghiocel. În celelalte n-1 case locuiesc colegele lui, câte una în fiecare casă. Ghiocel dorește să le ducă ghiocei la începutul lunii martie. Pentru că este leneș, Ghiocel se decide să ducă ghiocei doar colegelor care stau în case până la care Ghiocel are de parcurs cel mult k străzi. Ajutați-l pe Ghiocel să determine câtor colege ar putea să ducă ghiocei.
