Generarea cazurilor de testare | Set 5 (generând tablouri sortate aleatorii și palindrome)

Generând aleatoriu Tablouri sortate Depozităm elementele de matrice aleatorii într -un tablou și apoi îl sortăm și îl tipărește.

  Generând aleatoriu Palindrames

arhitectura de retea
  • Planul de generare a cazurilor de testare generează palindrome ciudate, precum și chiar lungime.
  • Planul de generare a cazurilor de testare folosește una dintre cele mai apreciate structuri de date Şi
  • Deoarece un palindrom este citit la fel de la stânga, precum și de dreapta, așa că am pus pur și simplu aceleași personaje aleatorii atât pe partea stângă (făcute folosind push_front () ) și partea dreaptă (făcută folosind push_back ( ))
