/*
 * Function:  ft_lstiter
 * --------------------
 * Iterates the list 'lst' and applies the function 'f'
 * to the content of each element.
 *
 *  lst: a pointer to the first element of the list
 *  f: a pointer to the function to be applied to the
 *     content of each element
 *
 *  This function first checks if `lst` or `f` is NULL.
 *  If so, it does nothing and simply returns.
 *
 *  If `lst` and `f` are not NULL, the function enters
 *  a `while` loop, which continues until the list
 *  becomes NULL (i.e., all elements of the list have
 *  been processed).
 *
 *  Inside the loop, the function calls the function 'f'
 *  on the 'content' of the current element, and then
 *  moves on to the next element by setting 'lst' equal
 *  to 'lst->next'.
 *
 *  Thus, the function goes through the entire list,
 *  applying the function 'f' to the content of each element.
