I have an array with list of elements and I need to print maximum count of element which is repeated consecutively. I have written a script for the same, but meanwhile looking for any alternative solution/logic exists for the same. 
use strict; use warnings;
use Data::Dumper;

my @a = ( 2,2,2,3,3,4,4 );

my (%hash, %count);
my $prev;

foreach ( 0..$#a ) {
    my $cur = $a[$_]; warn "cur:$cur\n";

    if ( ($prev && $cur != $prev || $_ == $#a) ) {

        my ($prev_key) = keys %count; 

        if ( !$prev_key ||( $count{$prev_key} ) <= $hash{$prev} ) {
            delete $count{$prev_key} if $prev_key;
            $count{$prev} = $hash{$prev};
        }
    }
    $hash{$cur}++;
    $prev = $cur;
}

warn Dumper \%count;

Output: 
$VAR1 = {
          '2' => 3
        };

The answer should be '3'. Since element '2' has occured consecutively '3' times in the array.
