Question

If i have three variables with integer and want to find which one is the largest one(not only the max integer), e.g if a is 3, b is 4 and c is 5, the I want to know c is the largest rather than return a 5 to me. How to achieve this or I should use

use List::Util

$d = max($a,$b,$c);
if($d == $a){}
elsif($d == $b){}
else{}

By using separate variables, you make pretty much anything impossible. Say you were using an array instead.

my @a = (3,4,5);

my $max_idx = 0;
for my $idx (1..$#a) {
   $max_idx = $idx
      if $a[$idx] > $a[$max_idx];
}

say $max_idx;
say $a[$max_idx];
