OPS1, k1, z1, RacunanjeElemenata

/*
 * Svaka od niti nezavisno izracunava i ispisuje prvih 5 elemenata svog niza prirodnih brojeva.
 * Za to vreme glavna nit ucitava red po red sa tastature i zavrsava rad celog programa kada
 * se ucita "Kraj".
 *
 * nitF --> fibonaci
 * nitK --> K_0 = 1, K_n = n^2;
