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.

[edit] Return value
1-4) Returns an iterator to the inserted element.
5-6) (none)
[edit] Exceptions
1-4) If an exception is thrown by any operation, the insertion has no effect.

[edit] 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) |

O(N*log(size() + N))
, where N is the number of elements to insert.[edit] See also
