You could try something like this:

#! perl -slw use strict; use Data::Dump qw[ pp ]; sub gen { my $href = shift; my @kByV = sort{ $href->{ $b } <=> $href->{ $a } } keys %$href; my @dist = ( $kByV[0] ) x $href->{ $kByV[0] }; shift @kByV; while( @kByV ) { my $k = shift @kByV; my $v = $href->{ $k }; my $n = int( @dist / ( $v+1 ) ); my $p = $n * $v; splice( @dist, $p, 0, $k ), $p -= $n for reverse 1 .. $v; } return \@dist; } pp gen( { A => 4, B => 2, C => 3, D => 1 } ); pp gen( { A => 5, B => 4, C => 3, D => 2, E => 1 } );

Outputs:

C:\test>1030688.pl ["A", "C", "B", "A", "D", "C", "B", "A", "C", "A"] ["A", "B", "C", "A", "D", "B", "C", "E", "A", "B", "D", "C", "A", "B", + "A"]
