/*
U ovom zadatku je bilo potrebno napraviti dvostruko spregnutu listu
i izvesti je kao staticku biblioteku.Zatim je potrebno napraviti dve funkcije.
Prva funkcija proverava da li jedan od elemenata ispunjava uslov koji smo zadali,
dok druga ima pokazivac na prvu funkciju i njome se sluzi kako bi ispitala sve elemente
u listi, i ukoliko ne ispunjava zadati uslov brisemo ih. Ovaj zadatak sam uradio tako sto
sam napravio listu studenata i izbacivao ih ukoliko ih je godina upisa starija od 2019.
