Progresie3

#2812

Se dă un șir de cel mult 106 numere naturale din intervalul [0,103]. Se cere să se verifice dacă există un număr natural r, astfel încât toate numerele distincte din șir să poată fi rearanjate, pentru a forma o progresie aritmetică de rație r. Se afișează numărul r, sau mesajul NU, dacă nu există un astfel de număr.
