#1136 Dragoni

Supărați că lansarea părții a treia a filmului lor preferat s-a amânat până în iunie 2018, Henry și Hetty s-au gândit la propriul scenariu pentru finalul trilogiei:

Într-o lume în care vikingii pot zbura cu dragonii există N insule. Hiccup, șeful tribului de vikingi aflat pe insula 1, știe M rute directe de zbor bidirecționale între insule. Pentru fiecare j intre 1 si M, ruta j unește insulele A j și B j și are lungime D j.

Pe fiecare insulă i, (1 ≤ i ≤ n) există dragoni din specia i care pot zbura fără a se opri pentru odihnă o distanță maximă Dmax i. Cu alte cuvinte, dragonii de pe insula i vor putea parcurge orice rută j, (1 ≤ j ≤ m) pentru care Dj ≤ Dmaxi, indiferent de ce alte drumuri au făcut anterior.

Hiccup dorește să ajungă de pe insula 1 pe insula N pentru a-l salva pe Toothless, dragonul lui. Pentru a ajunge acolo, el va lua inițial un dragon din specia 1 (de pe insula 1). Apoi, dacă la un moment dat Hiccup se află pe o insula i, (1 ≤ i ≤ n) având cu el un dragon din specia t, el poate:

  1. Să zboare de pe insula i pe o altă insulă x cu dragonul pe care îl are, folosind o rută directă j între insulele i si x, bineînțeles doar dacă Dj ≤ Dmaxt.
  2. Să schimbe dragonul din specia t pe care îl are cu un dragon din specia i aflat pe insula respectivă.

Cerințe:

a. Să se determine distanța maxima Dmaxi caracteristică unui dragon la care Hiccup poate ajunge fără a schimba dragonul pe care l-a luat inițial de pe insula 1.
b. Să se determine distanța minimă pe care Hiccup trebuie să o parcurgă pentru a ajunge de pe insula 1 pe insula N.

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 Dragoni 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.
