Squaring a string of ones ((1x$_)**2) is very clever! This works for me up to 8, but 9 fails (because 111111111**2 = 1.23456789876543e+16). (Same for toolic's solution below...)

You can save one more character with $" instead of " ".

    It works for 9 on a 64 bit system, which is why I didn't notice it's broken, but it is indeed broken on 64 bit systems.

    You could try to fix it with something like this, but as is that's too long and I don't feel much like golfing it now.

    perl -e 'printf"%*.0f\n",$t+abs,(1x abs)**2for 1..($t=pop),1-$t..-1' 9
