Copy a sequence, removing consecutive values using a predicate.
first | An input iterator. |
last | An input iterator. |
result | An output iterator. |
binary_pred | A binary predicate. |
Copies each element in the range [first,last) to the range beginning at
result
, except that only the first element is copied from groups of consecutive elements for which binary_pred
returns true. unique_copy() is stable, so the relative order of elements that are copied is unchanged.
