#1604
DMin
Se consideră un graf neorientat conex 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 muchii al unui lanţ elementar care uneşte x
cu y
.
Se dau k
perechi de vârfuri x y
. Determinați pentru fiecare pereche distanța de la x
la y
.
