Stiu ca e normal sa returneze ce gaseste numai ca imi returneaza doar in
consola, este normal si cand redirectez la /dev/null sa nu se blocheze insa
in prog test.c daca apelez system de aceasta comanda nu isi mai revine :(,
nu mai afiseaza codul de dupa, insa testele urmatoare se ruleaza. I don't
get it :((


am dat restart la masina virtuala si se comporta la fel :(.
