`#4404` Conflicte C++

RAU-Gigel își amintește cu nostalgie de momentele sale de început într-ale programării, când mai făcea și stângăcii cum ar fi să declare un nume de tipul int…. așa a apărut următoarea problemă:

Să ne imaginăm harta politică a lumii viitorului, împărțită în țări ale căror nume sunt de fapt numere naturale nenule. Între ele există anumite relații: două țări sunt înfrățite dacă au în compunerea numelui lor aceleași cifre (nu contează numărul de apariții), în timp ce două țări se află în conflict dacă nu au nicio cifră comună în numele lor.

Interesat de politică, RAU-Gigel ar vrea să afle câteva informații: câte țări sunt izolate din punct de vedere politic, în sensul că nu sunt înfrățite cu nicio altă țară? Pentru fiecare țară dintr-o listă de țări preferate să se afle: cu câte țări este înfrățită și cu câte în conflict?

Ajutați-l pe RAU-Gigel să afle răspunsul la întrebările sale !

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 Conflicte 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.
