Hi Gareth,

Just use hinted insertion like:

 Â  m.insert(m.end(),x);

As it happens, the hint in hinted insertion is used for *all* indices,
so providing m.end()
does indeed indicate that insertion should happen as close as possible
to the end of
*each* index.

Is this what you're after? Best regards,
