#2014 Canguri

La proba de atletism s-au calificat trei canguri care trebuie să efectueze sărituri pe o pistă de 800 metri.
Fiecare cangur se aliniază la linia de start, îşi lipeşte pe marsupiu eticheta cu numărul său de concurs iar apoi când se dă stratul efectuează săritură după săritură până trece linia de sosire.

Cunoscând lungimea săriturii fiecărui cangur (exprimată în metri) şi faptul că nu există doi canguri cu sărituri de aceeaşi lungime, scrieți un program care să determine:

a) Numărul de concurs al cangurului care ajunge primul la linia de sosire;
b) Numărul săriturilor efectuate de cangurul care a trecut primul linia de sosire.

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 Canguri 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.
