Assume that you want to create a linked list structure for 'item's. You are givenIn our implementations we used first and last pointers to keep first items and last item of linked list. Once we add new item, a new structure is created and added as last item.

Assume that we have only first pointer, and do not have last pointer. Complete the following function to add an item to at the beginning $($front$)$ of Linked Listed using only "first" pointer. Just submit function implementation, not the whole program.

bool Bag::insertFront$($string str$)$

$\{$
