#4243

Un experiment urmăreşte comportarea unui şoricel pus într-o cutie dreptunghiulară, împărţită în n x m cămăruţe egale de formă pătrată. Fiecare cămăruţă conţine o anumită cantitate de hrană. Şoricelul trebuie să pornească din colţul (1, 1) al cutiei şi să ajungă în colţul opus (n, m), mâncând cât mai multă hrană. El poate trece dintr-o cameră în una alăturată (două camere sunt alăturate dacă au un perete comun), mănâncă toată hrana din cămăruţă atunci când intră. Se asemenea, nu va intra niciodată într-o cameră fără hrană. Stabiliţi care este cantitatea maximă de hrană pe care o poate mânca.

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 mouse 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!
