Cifru1
#1061

Costel a descoperit într-o debara servieta cu cifru a tatălui său. Cifrul este compus din 4 discuri metalice pe care sunt inscripţionate cifrele de la 0 la 9. Fiecare disc se poate mişca individual, de sus în jos sau de jos în sus, formându-se combinaţii de cifre. De multe ori, datorită comodităţii, combinaţia ce permite deschiderea servietei este formată numai din cifre identice: 0000, 1111 etc.

Costel îşi imaginează un cifru compus din N discuri metalice, fiecare având inscripţionate cifrele de la 0 la 9, fiecare putând fi deplasat în cele două direcţii specificate anterior. Prin mutare Costel înţelege deplasarea unui disc în sus sau în jos, cu o singură poziţie, adică deplasarea discului până la cifra precedentă, respectiv următoare celei curente.

Realizaţi un program care, cunoscând poziţia iniţială a fiecărui disc dintre cele N discuri ale cifrului, determină şi afişează:

a) cifra cea mai mare care apare pe discurile cifrului în forma iniţială;
b)
b1) numărul minim de mutări necesare pentru ca numărul obţinut pe cifru să fie compus numai din cifre identice, număr necesar deschiderii servietei;
b2) cifra cea mai mică ce se poate obţine în urma efectuării numărului minim de mutări determinat;
b3) numărul de combinaţii formate din cifre identice, care se poate obţine în urma efectuării numărului minim de mutări determinat.

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 Cifru1 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!
