\begin{itemdescr}
\pnum
\effects
Adds elements to \tcode{c} as if by:
\begin{codeblock}
for (; first != last; ++first) {
value_type value = *first;
c.keys.insert(c.keys.end(), std::move(value.first));
c.values.insert(c.values.end(), std::move(value.second));
}
\end{codeblock}
Then, merges the sorted range of newly added elements and
the sorted range of pre-existing elements into a single sorted range; and
finally erases the duplicate elements as if by:
\begin{codeblock}
auto zv = ranges::zip_view(c.keys, c.values);
auto it = ranges::unique(zv, key_equiv(compare)).begin();
auto dist = distance(zv.begin(), it);
c.keys.erase(c.keys.begin() + dist, c.keys.end());
c.values.erase(c.values.begin() + dist, c.values.end());
\end{codeblock}
Equivalent to \tcode{insert(first, last)}.

\pnum
\complexity
Linear in $N$, where $N$ is \tcode{size()} after the operation.

\remarks
Since this operation performs an in-place merge, it may allocate memory.
