`#2484` key

Cristi are în sertar n chei vechi; fiecare a costat o anumită sumă exprimată în lei și fiecare a fost făcută pentru a deschide aceeași ușă. Atât cheile cât și ușa au un cod format din 3 litere. Din păcate, unele chei s-au deteriorat și Cristi le-a împărțit în 4 categorii:
stricate – nicio o literă din codul cheii nu coincide cu litera de pe aceeași poziție din codul ușii, iar pentru a o repara trebuie sa plătească prețul integral al cheii;
deteriorate – exact o litera din codul cheii coincide cu litera de pe aceeași poziție din codul ușii, iar pentru a o repara trebuie sa plătească două treimi din prețul cheii;
slab deteriorate – exact două litere din codul cheii coincid cu literele de pe aceleași poziții din codul ușii, iar
pentru a o repara trebuie sa platească o treime din prețul cheii;
bune – codul cheii e identic cu codul ușii, iar cheia nu trebuie reparată;
Cerințe:
1) Să se afle câte chei din fiecare categorie are Cristi.
2) Sa se afle cât a plătit Cristi pentru a repara toate cheile.

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 key 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.
