Culori2
#1031

Pasiunea Mirunei este să coloreze. Vacanţa trecută şi-a petrecut-o la bunica ei la ţară şi pentru că se cam plictisea s-a gândit să vopsească gardul de la casa bunicii.

Gardul este compus din N scânduri dispuse una lângă alta. Miruna a găsit în garajul bunicii 5 cutii de vopsea de culori diferite: albă, albastră, roşie, verde şi galbenă. Când a vopsit gardul, Miruna a respectat următoarele reguli:
  1. Dacă o scândură era vopsită cu alb, următoarea scândură o vopsea obligatoriu cu albastru
  2. Dacă o scândură era vopsită cu albastru, atunci următoarea scândură o vopsea cu alb sau roşu
  3. Dacă o scândură era vopsită cu roşu, atunci următoarea scândură o vopsea cu albastru sau verde
  4. Dacă o scândură era vopsită cu verde, atunci următoarea scândură o vopsea cu roșu sau galben
  5. Dacă o scândură era vopsită cu galben, atunci următoarea scândură o vopsea obligatoriu cu verde

După ce a și-a terminat treaba Miruna își admira “opera de artă” și se întreba în câte moduri diferite ar fi putut să vopsească gardul bunicii.

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 Culori2 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!
