În laboratoarele Marii Ghilde, ucenicul Jean Carapace are pe masa de lucru N eprubete asezate in linie. Eprubetele sunt numerotate de la stanga la dreapta cu indici de la 1 la N. Fiecare eprubetă i conține inițial o cantitate de Esență Primordială, V[i] , număr natural nenul. Definim o „Pereche Pură” ca fiind două eprubete vecine ale căror cantități sunt reprezentate prin numere prime între ele, adică cmmdc(V[i] , V[i+1]) = 1. O proprietate esențială a configurației inițiale este că se garantează existent, a a cel puțin unei astfel de perechi.
Scopul lui este să obțină „Scara Perfectă”, adică o configurație în care cantitatea de esență din fiecare eprubetă este
egală cu indicele ei:
Eprubeta ₁ = 1, Eprubeta ₂ = 2, …, Eprubeta _N = N.
Pentru a modifica nivelul substanței, el poate folosi doar fenomenul de Rezonanță între două eprubete vecine. Mai exact, operațiile se aplică pe două eprubete situate la indicii A și B, cu condiția ca |A − B| = 1. Operațiile permise sunt:
adun A B ⇒ V[A] ← V[A] + V[B] (Eprubeta A câștigă o cantitate de esență egală cu valoarea din eprubeta B)
scad A B ⇒ V[A] ← V[A] − V[B] (Eprubeta A pierde o cantitate de esență egală cu valoarea din eprubeta B)
La aplicarea operațiilor, trebuie respectate următoarele reguli:
1. La fiecare operație, doar eprubeta cu indicele A își modifică valoarea. Eprubeta cu indicele B rămâne neschimbată.
2. Cantitatea de esență din orice eprubetă trebuie să se mențină în intervalul de siguranță [1, 10sup>5] în orice moment (inclusiv intermediar).
3. Numărul total de operații nu poate depăși 10⁶.
Se cunosc C (numărul cerinței, 1 sau 2), N numărul de eprubete, precum și valorile V[i]. Determinați:
Secvența de lungime maximă din șir în care oricare două eprubete alăturate formează o Pereche Pură, dacă C = 1. Dacă există mai multe astfel de secvențe, se va afișa cea cu indicele de început minim.
O succesiune de operații care transformă șirul inițial în Scara Perfectă, respectând toate regulile de mai sus, dacă C = 2.

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 Alchimie 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!
