ModificaParanteze
Fie un șir de paranteze rotunde, deschise sau închise. Putem efectua de câte ori dorim operația de transformare a unei paranteze deschise într-una închisă sau invers. Să se determine numărul minim de operații necesare transformării secvenței inițiale într-una corect parantezată. Dacă acest lucru nu este posibil, se va afișa -1
