#2972 rufe

Alex vrea să își usuce rufele pe balcon. El a spălat K tricouri și o șosetă. Uscătorul lui Alex are N niveluri, iar fiecare nivel are M locuri unde poate atârna câte un singur obiect de îmbrăcăminte. Alex usucă hainele într-un mod specific: începe prin a pune șoseta pe nivelul A, locul B, iar apoi aduce coșul de rufe cu cele K tricouri și le așază pe rând, mereu alegând o poziție liberă cât mai depărtată de locul unde a pus șoseta. Metrica pe care o găsește ca fiind cea mai potrivită când vine vorba de uscatul rufelor este distanța Manhattan, astfel încât distanța de la nivelul r1, locul c1 la nivelul r2, locul c2 are valoarea expresiei |r1 – r2| + |c1 - c2|. Aflați distanța dintre poziția unde a atârnat ultimul tricou și poziția unde se usucă șoseta.

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 rufe 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.
