I have what I thought would be a very simple problem. However, it has me baffled. I have data of the form
which I would like to split into the form of
"01 02 03 04 05 06"
. The code that I wrote
my @list = split(/(..)/, '010203040506');
print join(' ', @list)
does the job, but produces empty elements in the list, which results in the undesired output of
" 00 01 02 03 04 05 06"
which contains unwanted spaces. I understand why this is: when splitting on any two characters, the first two are a match, thus, thus they represent the split string (which is element 1), which separates a NULL string (captured in element 0) from the remaining characters (captured in remaining characters). However, I don't want to see the extra spaces in the resulting output. How can I get rid of that?
