Re: sorting based on a list

in reply to sorting based on a list

my @indicies = sort { $list[$a] cmp $list[$b] } 0..$#list; my @rearranged = @list2[@indicies];

-- Randal L. Schwartz, Perl hacker


update: Hold on. I solved the problem he stated. Not the problem he had. OK, nothing cannot be solved without a bit of indirection:
my @indicies = sort { $list[$a] cmp $list[$b] } 0..$#list; my @rearranged; @rearranged[@indicies] = sort @list2;
There. Make a sorted @list2 be disordered in the same way that @list is.

Also see my other solution.
