Sorts non-negative integers only. The extension to negative values seemed a distraction from this fun task.

=={{header|Groovy}}==

Solution:

final nPoles = list.max()

list.collect {

beadTally.findAll{ it }.size()

}

 

Annotated Solution (same solution really):

final nPoles = list.max()

// each row is a number tally-arrayed across the abacus

beadTalliesDrop.collect{ beadTally -> beadTally.findAll{ it }.size() }

The program below handles integers and not just whole numbers. As are so many others, the solution is limited by the lack of sparse array or list compression.

Here we simulate the dropping beads by using the <tt>push</tt> method.

my @rods;

for words ^«@list -> $x { @rods[$x].push(1) }

}

 

The <tt>^</tt> is the "upto" operator that gives a range of 0 up to (but not including) its endpoint. We use it as a hyperoperator (<tt>^«</tt>) to generate all the ranges of rod numbers we should drop a bead on, with the result that <tt>$x</tt> tells us which rod to drop each bead on. Then we use <tt>^</tt> again on the first rod to see how deep the beads are stacked, since they are guaranteed to be the deepest there. The <tt>[+]</tt> adds up all the beads that are found at level <tt>$y</tt>. The <tt>last</tt> short circuits the map so we don't have to look for all the missing beads at a given level, since the missing beads are all guaranteed to come after the existing beads at that level (because we always dropped left to right starting at rod 0).

 

 

Zero, negative, and duplicate integers (values) can be handled.
