`#1824` Pitic

Carmen, piticul de gradina vrea sa meargă în vizita la piticul Tulosba. Pentru a ajunge la Tulosba, Carmen trebuie sa meargă printr-o rețea de N galerii, fiecare alcătuită din M sectoare.

Rețeaua poate fi reprezentată printr-un tablou cu N linii, numerotate de la 1 la N și M coloane, numerotate de la 1 la N. Carmen ocupă sectorul 1 al galeriei 1. Tulosba ocupă sectorul M al galeriei 1.

La galeria n se termina rețeaua și începe gradina unde sunt niște copii răi care vor sa-l spargă pe Carmen cu bâtele de Baseball.

Dacă sectorul curent a lui Carmen este (i,j), atunci se poate deplasa:

La dreapta, ajungând în sectorul (i,j+1) .
Pe diagonala la dreapta în sus, ajungând în sectorul (i-1,j+1).
Pe diagonala la dreapta în jos, ajungând în sectorul (i+1,j+1).

Sa se afișeze în câte moduri poate Carmen sa ajungă la Tulosba.

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 Pitic 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.
