Requirement

Description

seq

A model of Forward Sequence

Operation's argument

pos

A model of Forward Iterator

The position to insert at

range

A model of Forward Sequence

Range to insert


Expression Semantics
insert_range(seq, pos, range);

Return type:

Semantics: Returns a new sequence, containing all the elements of seq, and the elements of range inserted at iterator pos. All elements retaining their ordering from the orignal sequences.

Complexity

Constant. Returns a view which is lazily evaluated.
