Dear monasterians,
i've built a generator of integer partitions of n which gives you all the sets of nonzero integers that add up to exactly n.

the code (i'm terribly sorry about the names of the variables. and there are few bugs that you'll be able to see as you run it):

#!/usr/bin/perl -w print 'enter n : '; $kk = $n = $nn = readline(*STDIN); my @ready = @aa = (); while ($n) {$aa[$n] = 1;$n--;} @bb = @aa; while ($kk) { $aa[$nn - $kk + 1] += $aa[$nn - $kk]; $aa[$nn - $kk]=''; $ready[($nn - $kk)*3] = "@aa\n"; $aa[$kk - 1] += $aa[$kk]; $aa[$kk]=''; $ready[($nn - $kk)*3 + 1] = "@aa\n"; $aa[$nn - $kk + 1] += $aa[$nn - $kk]; $aa[$nn - $kk]=''; $ready[($nn - $kk)*3 + 2] = "@bb\n"; $bb[$kk - 1] += $bb[$kk]; $bb[$kk]=''; $kk--;} print @ready;

so my "questions" is if there's a way to make a few improvments ?
