void insert( std::initializer_list<value_type> ilist );		(6)	(since C++11)

Inserts element(s) into the container.

1-2) Inserts value. If the container has elements with equivalent key, inserts at the upper bound of that range.(since C++11).

3-4) inserts value in the position as close as possible, just prior(since C++11), to hint.

5) inserts elements from range [first, last).

6) inserts elements from initializer list ilist.

No iterators or references are invalidated.

Parameters

hint	-	iterator, used as a suggestion as to where to start the search (until C++11) iterator to the position before which the new element will be inserted (since C++11)
value	-	element value to insert
first, last	-	range of elements to insert
ilist	-	initializer list to insert the values from
Type requirements
- InputIt must meet the requirements of InputIterator.

Return value

1-4) Returns an iterator to the inserted element.

5-6) (none)

Exceptions

1-4) If an exception is thrown by any operation, the insertion has no effect.

Complexity

1-2) Logarithmic in the size of the container, O(log(size())).

3-4) Amortized constant if the insertion happens in the position just after the hint, logarithmic in the size of the container otherwise.	(until C++11)
3-4) Amortized constant if the insertion happens in the position just before the hint, logarithmic in the size of the container otherwise.	(since C++11)

5-6) O(N*log(size() + N)), where N is the number of elements to insert.
