Common sorted list: Difference between revisions

=={{header|Nim}}==

We could use a <code>HashSet</code> or an <code>IntSet</code> to deduplicate. We have rather chosen to use the procedure <code>deduplicate</code> from module <code>sequtils</code> applied to the sorted list.

<lang Nim>import algorithm, sequtils

proc commonSortedList(list: openArray[seq[int]]): seq[int] =

sorted(concat(list)).deduplicate(true)

echo commonSortedList([@[5,1,3,8,9,4,8,7], @[3,5,9,8,4], @[1,3,7,9]])</lang>

{{out}}

<pre>@[1, 3, 4, 5, 7, 8, 9]</pre>
