palindrom4
Un număr se numește palindrom dacă citit de la stânga la dreapta este identic cu numărul citit de la dreapta la stânga. Un număr care nu este palindrom poate fi transformat în palindrom adăugând la dreapta sa una sau mai multe cifre. Dat fiind un șir de n
numere naturale, scrieți un program care să rezolve următoarele două cerințe:
1. să se determine numărul minim total de cifre care trebuie să fie adăugate, astfel încât fiecare valoare din șir să fie palindrom;
2. considerând că putem adăuga cel mult S
cifre, să se determine numărul maxim de termeni palindrom aflați pe poziții consecutive în șirul obținut.
