Hello Monks,

Within a list , I want to ignore a section of numbers that start with 6 and extending to the 7 My code below does that only for the first set of numbers . I am trying to splice the array on the copy and not original array But looks like the loop ends before it can read the next 6 in the list . Not looking for any grep or regex solution for this task . 

#!/usr/bin/perl
use warnings;
use strict;
use Data::Dumper;
########

 my $aref = [1, 6, 2, 2, 7, 1, 6, 99, 99, 7];
 my $flag = 0;
 my $i = 1;
 my $sixindex = 0;
 my @copy = @$aref;
if (scalar(@$aref) >= 2) {
    foreach my $x (0..$#{$aref}) {
        if (defined($aref->[$x])) {
           if ($aref->[$x] == 6) {
             $flag = 1;
             $sixindex = $x;
             next;
           }

             if ($flag) {
               unless ($aref->[$x] == 7) {
                 $i++;
                 next;
              } elsif ($aref->[$x] == 7 ) {
                 splice(@copy, $sixindex, $i + 1);
                 $flag = 0;
                 $i = 1;
                 $sixindex = 0;
                 next;
              }
          }
      }
    }
}

print Dumper \@copy;
