    Function: ft_lstiter
    Purpose: Applies a function to the content of each element in a list.
    How it works:
       - Checks if 'lst' and 'f' are not NULL to proceed.
       - Iterates through each element in the list.
       - Applies function 'f' to the content of each element.
       - Does not return anything.
       - Note: The list navigation is done using 'lst = lst->next'.
