Re^4: Challenge: sort weekdays in week-order (elegantly and efficiently)

No need for that, just tweak the "tr" a little :)

#!/usr/bin/perl

use strict; # https://perlmonks.org/?node_id=11145633
use warnings;
use List::AllUtils qw( shuffle sort_by );

my @weekdays = shuffle
  qw/Monday tuesday wednesday friday sunday Saturday Thursday/;

print "$_\n" for sort_by { lc =~ tr/muwht/a-d/dr } @weekdays; # Monday
+ first
print "\n";
print "$_\n" for sort_by { lc =~ tr/nmewhfatsu/a-g/dr } @weekdays; # S
+unday first

Should also work: `print "$_\n" for sort_by { lc =~ tr/hfst/x-z/dr } @weekdays; # Monday +first print "\n"; print "$_\n" for reverse sort_by { scalar reverse lc =~ tr/rn/at/dr } +@weekdays; # Sunday first` [download]	[reply] [d/l]

Nice! It just shifted from magic to deep magic. :) "It's not how hard you work, it's how much you get done."	[reply]
