`#2617` Taieturi

Gigel are o bucată de hârtie cu dimensiunile N*M și vrea să o taie în bucăți cu dimensiunile 1*1, respectând regulile:

poate să taie o singură foaie la un moment dat. Nu poate suprapune mai multe foi și să le taie în același timp;
fiecare tăietură se face dintr-o parte în alta a foii, pe verticală sau orizontală.

Scrieți un program care să citească numerele N și M și să determine numărul de tăieturi care trebuie efectuate.

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 Taieturi 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.
