Re^2: Finding the max()/min()

Perhaps this will count as "cheating" for the purpose of this thread, but I just do this to find the min/max of a list

use List::Util qw(min max);
$min = min @list;
$max = max @list;

A moderate annoyance of List::Util::m(in\|ax) is that they dont operate on tied values or situations where there is some form of indirection involved (like finding the key whose value in a hash is the lowest). Then List::Util::reduce() is your friend: `$min = reduce { ($a,$b)[$a < $b] } @list; $min_key = reduce { ($a,$b)[$x{$a} < $x{$b}] } keys %x;` [download] Working out max is left as an exercise :-) --- demerphq	[reply] [d/l]
