#2022 gard1

Vrăjitorul Arpsod este deranjat la culme de câinii vecinului. Aceștia au prostul obicei de a veni să-și îngroape oasele în curtea vrăjitorului. Înainte de a lua măsuri drastice împotriva vecinului, Arpsod a decis să construiască un gard despărțitor între cele două curți. Gardul poate fi privit ca un segment de dreaptă de lungime N metri. Astfel, Arpsod a angajat K meseriași pentru a-i construi gardul. Fiind un tărâm cât se poate de democratic, fiecare muncitor a decis că el este dispus să construiască doar o parte din gard pornind de la al x-lea metru și pană la al y-lea metru inclusiv. Fiecare meseriaș cere o anumită sumă de bani pentru lucrarea sa.

Arpsod poate decide să angajeze o parte dintre muncitori, pentru a realiza întregul gard. Dacă doi muncitori angajați au de construit o porțiune comună a gardului, ea va fi lucrată de amândoi, dar fiecare își va primi integral suma solicitată.

Ajutați-l pe Arpsod să-și aleagă meseriașii astfel încât gardul să fie construit integral și el să plătească o sumă minimă de bani.

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 gard1 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.
