4. Merge Tag (Control Tags) Example
The merge tag is a generic tag that is used to
merge iterators. The successive call to the
merge iterator causes each merge iterator to
have a chance to expose its element,
subsequently next call allows the next iterator
to expose its element. Once the last iterator is
done exposing its element, the first iterator is
allowed to do so again (unless it is exhausted
of entries). In the current example, 2 lists being
merged where each list have 5 entries.
