#2492 pqstr

Se dau două numere naturale P şi Q şi un şir S = S[1], S[2], …, S[N] de numere întregi. Din şirul S trebuie ales un (P,Q)-subşir S[i1], S[i2], …, S[ik] astfel încât k ≥ 2 și P ≤ ij – ij-1 ≤ Q pentru orice j=2..k.
De exemplu, pentru P=2, Q=3 şi S=(2,-3,-7,-8,5,-1), subşirul (2,-3,-8) nu este (2,3)-subşir, dar subşirurile (2,-7,5) și (2,-7,-1) sunt (2,3)-subşiruri.
Pentru orice (P,Q)-subşir X = (S[i11],S[i2], ...,S[ir]), ne interesează valoarea expresiei
e(X) = |S[i1] - S[i2]| + |S[i2] - S[i3]| + ... + |S[ir-1] - S[ir]|
unde cu |a| s-a notat modulul numărului întreg a.
Să se calculeze şi să se afişeze E = max{e(X), X este (P,Q)-subşir al lui S}.

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 pqstr 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.
