#4078

Matei, care locuiește in orașul p, vrea să ajungă in orașul q să il viziteze. El are o hartă pe care se află n orașe și m drumuri prin care poate să treacă pentru a ajunge la destinație. Pe hartă apare și durata de timp td pentru fiecare drum, care reprezintă numărul de minute în care este parcurs drumul și to pentru traversarea orașelor (unele orașe sunt mai aglomerate, iar altele nu). Matei vrea să ajungă cat mai rapid la destinație, dar dacă există mai multe trasee de timp minim, il va alege pe acela care trece prin mai multe orașe. Nu vor exista trasee de timp minim cu același număr de orașe. Ajutati-l pe Matei să gasească drumul cerut.
