in thread Replacing values in an array

Using for instead of map:

use strict; use warnings; use Data::Dumper; my @a = ("M94202", "M94150", "M94297", "M94150", "M94161", "M94161", " +M94162"); my ( $n, %h ) = -1; $_ = $h{$_} //= $n+=2 for @a; print Dumper \@a;

I suppose if you were playing golf, without use strict, you might write:

my ( $n, %h ) = -1; $_ = $h{$_} //= $n+=2 for @a;
in one-line as:
$_=$h{$_}//=$}+=2-!$}for@a;

[ambrus]: And even when I traveled on a big plane for a long flight, it had 3 seats, then corridor, then 4 seats, then corridor, then 3 seats, so less than half of the people sit between two other dudes.
