#3446 Ateleport

Marian se află în galaxia OJI-2020 și este anul 11235. În această galaxie există N planete diferite și M canale bidirecţionale de transport de tipul (x, y, t) care îţi permit să te deplasezi de pe planeta x pe planeta y (sau invers) în t secunde.

Dar Marian este un adevărat inginer și, pentru că i se pare foarte ineficientă această metodă de transport, a dezvoltat un dispozitiv care îți permite teleportarea de pe o planetă x pe orice altă planetă y în P secunde cu condiţia că ai putea ajunge pornind de pe planeta x pe planeta y folosind maxim L canale de transport.

Acest dispozitiv este momentan doar un prototip, așa că nu îl poate folosi mai mult de K ori. Marian se află pe planeta 1 și te roagă să îi spui care e timpul minim necesar pentru a ajunge pe planeta N.

Să se scrie un program care calculează timpul minim necesar pentru a ajunge pe planeta N pornind de pe planeta 1.

OJI 2020, clasele XI-XII

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 Ateleport 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.
