Write the pseudo code of member function

insert(const value_type& entry).

The function will insert a new copy of entry in the sequence before the current item. If there was no current item, then the new entry has been

inserted at the front. In either case, the new item is now the current item of the sequence. Analyze the running time of your pseudo code in big O notation. Write the pseudo code of member function remove_current()

. The current item will be removed from the sequence, and the item after this (if there is one) is now the new current item. Analyze the running time of your pseudo code in big O notation.
