#2736 Baza De Date

Se citește numărul n și apoi n articole cu structura prenume nume salariu vârstă funcție număr_de_telefon email. Fiecare articol este plasat pe câte o linie, câmpurile sale fiind separate prin câte un spațiu. Câmpurile salariu și vârstă conțin numere naturale, celelalte conțin șiruri de caractere.

Se citește apoi un număr natural p cuprins între 1 și 7 și un caracter c care poate fi + sau -.

Se cere ordonarea celor n articole în funcție de p și c, astfel:

  • dacă p=1, ordonarea se face după prenume; dacă p=2, ordonarea se face după nume; dacă p=3, ordonarea se face după salariu; dacă p=4, ordonarea se face după vârstă; dacă p=5, ordonarea se face după funcție; dacă p=6, ordonarea se face după număr_de_telefon; dacă p=7, ordonarea se face după email;
  • dacă c are valoarea +, ordonarea va fi crescătoare, iar dacă c are valoarea -, ordonarea va fi descrescătoare;
  • dacă două articole au aceeași valoare a câmpului în raport cu care se face sortarea, ordinea lor nu se va modifica.

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 Baza De Date 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.
