iterator lower_bound( const Key& key );	(1)
const_iterator lower_bound( const Key& key ) const;	(1)

1) Returns an iterator pointing to the first element that is not less than key.

2) Returns an iterator pointing to the first element that compares not less to the value x. This overload only participates in overload resolution if the qualified-id Compare::is_transparent is valid and denotes a type. They allow calling this function without constructing an instance of Key.

Parameters

key	-	key value to compare the elements to
x	-	alternative value that can be compared to Key

Return value

Iterator pointing to the first element that is not less than key. If no such element is found, a past-the-end iterator (see end()) is returned.

Complexity

Logarithmic in the size of the container.
