I don't get to play with one-liner obfu/golf too often, so thought I'd try this question :) Prints an empty line in between any missing numbers.

perl -le 'for(<>){/(.*?)(\d+)/;$h{$2}=$1;$a=$2if$2>$a;}for(1..$a){print$h{$_}||""}' c.txt

Input:

today 5
tomorrow 3
but not as 2
anything can 11
what the hell 4
I don't know 6
I'm outta here! 10
