Bomber

#841

Se consideră un poligon militar, pe care este stabilit un sistem de axe de coordonate xOy. Se dau n bombe, numerotate de la 1 la n, pentru fiecare cunoscându-se coordonatele x y și puterea de distrugere p. La explozia unei bombe de putere p se va distruge totul în interiorul și pe cercul de centru x y și rază p, iar dacă există alte bombe în această zonă, vor exploda la rândul lor.

Dându-se numărul de ordine al unei bombe care explodează, să se determine câte bombe rămân intacte la finalul șirului de explozii declanșate.

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 Bomber 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.

Du-te sus!
