By writing s/^(.*) \1$/$1/m|... I could get rid of the g (gaining one stroke) by piggybacking on the while loop to remove all the duplicates. A slight disadvantage is that the runtime is considerably longer -- the large test cases take a few seconds to complete -- but it stays in the "reasonable" frame. > $_&&& This is good. I struggled for quite some time with a $_&&die statement at the end (the funkiest way to write it that I found was ??&&die, but still it was too long) when I thought of the divide-by-zero trick that many players used, hence: 1/!$_ which is exactly the same length (but I've seen a/!//, which i like better) and dies when the input string is not-empty (hence !$_ is equal to zero) as it tries to divide by zero. Otherwise, my solution is the same as Ala's. pom
