DrumuriMinime

#4162

Se consideră un graf orientat cu n vârfuri, numerotate de la 1 la n, şi m muchii. Definim distanţa minimă dintre două noduri x şi y ca fiind numărul minim de arce al unui drum elementar care uneşte x cu y.

Se dau k perechi de vârfuri x y. Determinați pentru fiecare pereche distanța minimă dintre x și y.
