Inserts elements to specified position in the container.

1-2) inserts value before the element pointed to by pos

3) inserts count copies of the value before the element pointed to by pos

4) inserts elements from range [first, last) before the element pointed to by pos

5) inserts elements from initializer list ilist.

All iterators are invalidated. References are invalidated too, unless pos == begin() or pos == end(), in which case they are not invalidated.

Parameters

pos	-	element before which the content will be inserted
value	-	element value to insert
first, last	-	the range of elements to insert, can't be iterators into container for which insert is called
ilist	-	initializer list to insert the values from

Return value

1-2) iterator pointing to the inserted value

3) iterator pointing to the first element inserted, or pos if count==0.

4) iterator pointing to the first element inserted, or pos if first==last.

5) iterator pointing to the first element inserted, or pos if ilist is empty.

Complexity

1-2) Constant plus linear in the lesser of the distances between pos and either of the ends of the container.

3) Linear in count plus linear in the lesser of the distances between pos and either of the ends of the container.

4) Linear in std::distance(first, last) plus linear in the lesser of the distances between pos and either of the ends of the container.

5) Linear in ilist.size() plus linear in the lesser of the distances between pos and either of the ends of the container.
