#4078 Distanta

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.

Cum funcționează evaluarea?

www.pbinfo.ro permite evaluarea a două tipuri de probleme:

  • probleme la care rezolvarea presupune scrierea unui program complet
  • probleme la care rezolvarea presupune scrierea unei secvențe de program - câteva instrucțiuni, o listă de declarații, una sau mai multe funcții, etc.

Problema Distanta face parte din prima categorie. Soluția propusă de tine va fi evaluată astfel:

  • Programul sursă este compilat folosind compilatorul corespunzător. Dacă în urma compilării se obțin erori sau avertismente, acestea sunt afișate în această pagină.
  • Dacă programul a fost compilat, executabilul obținut va fi rulat, furnizându-i-se unul sau mai multe seturi de date de intrare, în concordanță cu restricțiile specifice problemei. Pentru fiecare set de date se obține un anumit punctaj, în raport cu corectitudinea soluției tale.

Suma punctajelor acordate pe testele utilizate pentru verificare este 100. Astfel, soluția ta poate obține cel mult 100 de puncte, caz în care se poate considera corectă.
