Template:cpp/container/lower bound

@1,2@ Returns an iterator pointing to the first element that is not less than (i.e. greater or equal to).

@3,4@ Returns an iterator pointing to the first element that compares not less (i.e. greater or equal) to the value.

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

Complexity
Logarithmic in the size of the container.
