Printing keys from a hash by value?by jms53 (Monk)
|on Jan 30, 2012 at 14:31 UTC||Need Help??|
jms53 has asked for the
wisdom of the Perl Monks concerning the following question:
Hello Monks, I have a hash table from which I would like to print 20 keys with the highest values. I currently have this code:
This returns numbers, and the following error message:Use of uninitialized value within %top_words in concatenation (.) or string at ./test.pl line 114.
I can't see the error, and line 114 is the print command. Thank you.
