Detailed Description
template<typename _Tp, typename _Alloc = allocator<_Tp>>class std::forward_list< _Tp, _Alloc >
A standard container with linear time access to elements, and fixed time insertion/deletion at any point in the sequence.
Meets the requirements of a container, a sequence, including the optional sequence requirements with the exception of at and operator[].
This is a singly linked list. Traversal up the list requires linear time, but adding and removing elements (or nodes) is done in constant
time, regardless of where the change takes place. Unlike std::vector and std::deque, random-access iterators are not provided, so
subscripting ( [] ) access is not allowed. For algorithms which only need sequential access, this lack makes no difference.
Also unlike the other standard containers, std::forward_list provides specialized algorithms unique to linked lists, such as splicing,
sorting, and in-place reversal.
A couple points on memory allocation for forward_list<Tp>:
First, we never actually allocate a Tp, we allocate Fwd_list_node<Tp>'s and trust [20.1.5]/4 to DTRT. This is to ensure that after elements
from forward_list<X,Alloc1> are spliced into forward_list<X,Alloc2>, destroying the memory of the second list is a valid operation, i.e.,
Alloc1 giveth and Alloc2 taketh away.

Removes the element pointed to by the iterator following pos. Parameters:
pos Iterator pointing before element to be erased.
Returns:
An iterator pointing to the element following the one that was erased, or end() if no such element exists.
This function will erase the element at the given position and thus shorten the forward_list by one.
Due to the nature of a forward_list this operation can be done in constant time, and only invalidates iterators/references to the element
being removed. The user is also cautioned that this function only erases the element, and that if the element is itself a pointer, the

last Iterator pointing to one past the last element to be erased.
Returns:

This function will erase the elements in the range (pos,last) and shorten the forward_list accordingly.
This operation is linear time in the size of the range and only invalidates iterators/references to the element being removed. The user is

Sort the elements of the list. Sorts the elements of this list in NlogN time. Equivalent elements remain in list order.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::splice_after (const_iterator__pos,
forward_list< _Tp, _Alloc > &&__list) [inline]
Insert contents of another forward_list. Parameters:
pos Iterator referencing the element to insert after.
list Source list.
The elements of list are inserted in constant time after the element referenced by pos. list becomes an empty list.
Requires this != x.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::splice_after (const_iterator__pos,
forward_list< _Tp, _Alloc > &&__list, const_iterator__i) [inline]
Insert element from another forward_list. Parameters:
pos Iterator referencing the element to insert after.
list Source list.
i Iterator referencing the element before the element to move.
Removes the element in list list referenced by i and inserts it into the current list after pos.

template<typename _Tp , typename _Alloc > void forward_list::splice_after (const_iterator__pos, forward_list< _Tp, _Alloc > &&__list,

Insert range from another forward_list. Parameters:
pos Iterator referencing the element to insert after.
list Source list.
before Iterator referencing before the start of range in list.
last Iterator referencing the end of range in list.
Removes elements in the range (before,last) and inserts them after pos in constant time.
Undefined if pos is in (before,last).

template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::swap (forward_list< _Tp, _Alloc > &__list)
[inline]
Swaps data with another forward_list. Parameters:
list A forward_list of the same element and allocator types.
This exchanges the elements between two lists in constant time. Note that the global std::swap() function is specialized such that
std::swap(l1,l2) will feed to this function.

template<typename _Tp, typename _Alloc = allocator<_Tp>> void std::forward_list< _Tp, _Alloc >::unique () [inline]
Remove consecutive duplicate elements. For each consecutive set of elements with the same value, remove all but the first one. Remaining
elements stay in list order. Note that this function only erases the elements, and that if the elements themselves are pointers, the
pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.

template<typename _Tp , typename _Alloc > template<typename _BinPred > void forward_list::unique (_BinPred__binary_pred)
Remove consecutive elements satisfying a predicate. Parameters:
binary_pred Binary predicate function or object.
For each consecutive set of elements [first,last) that satisfy predicate(first,i) where i is an iterator in [first,last), remove all but
the first one. Remaining elements stay in list order. Note that this function only erases the elements, and that if the elements themselves
are pointers, the pointed-to memory is not touched in any way. Managing the pointer is the user's responsibility.
