=====unique_copy=====
Syntax:

<code>
    #include <algorithm>
    iterator unique_copy( iterator start, iterator end, iterator result );
    iterator unique_copy( iterator start, iterator end, iterator result, BinPred p );
</code>

The unique_copy() function copies the range [start,end) to result, removing all
consecutive duplicate elements. If the binary predicate p is provided, then it
is used to test two elements to see if they are duplicates.

The return value of unique_copy() is an iterator to the end of the new range.

unique_copy() runs in [[/complexity|linear time]].
