Best way to store an array considering all matches like query?

this will help At first I thought you might be able to use the ARRAY_OVERLAP( ) function, but it appears that will provide you with a TRUE if there are any matches, not all elements match.
https://docs.snowflake.net/manuals/sql-reference/functions/arrays_overlap.html
code :
CREATE OR REPLACE TABLE array_demo (id INTEGER, array1 ARRAY);

INSERT INTO array_demo (id, array1)
    SELECT 1, array_construct(1, 2) UNION ALL
    SELECT 2, array_construct(2, 3) UNION ALL
    SELECT 3, array_construct(3, 4) UNION ALL
    SELECT 4, array_construct(1, 2, 3, 4, 5);

SET search_array = '[2,3]';

SELECT *
FROM   array_demo
WHERE  array_intersection(array1, parse_json($search_array)) = parse_json($search_array);
--returns two records, ids 2 and 4

Store Array of #s to NSUserDefaults, Add Checkmark to each cell row that matches a # in array

this will help Absolutely!
You can use the setObject:forKey: method to write an NSArray object to NSUserDefaults, and objectForKey: to retrieve that array.
code :
- (void)tableView:(UITableView *)tableView didSelectRowAtIndexPath:(NSIndexPath *)indexPath
[tableView cellForRowAtIndexPath:indexPath].accessoryType = UITableViewCellAccessoryCheckmark;

Perl regex store matches in array

Does that help It looks like you have a CSV File, so use an actual CSV parser for it like Text::CSV.
After you parse the columns, you can separate your first field into the array:
code :
use strict;
use warnings;

use Text::CSV;

my $csv = Text::CSV->new ( { binary => 1 } )  # should set binary attribute.
    or die "Cannot use CSV: ".Text::CSV->error_diag ();

my $line = qq{"229269_2,190594_2,94552_2,266076_2,269628_2,165328_2,99319_2,263339_2,263300_2,99315_2,271509_2,2714",A,1 the next line could look like 84545,X,2};

if ($csv->parse($line)) {
    my @columns = $csv->fields();
    my @nums = split ',', $columns[0];

    print "@nums\n";
}
229269_2 190594_2 94552_2 266076_2 269628_2 165328_2 99319_2 263339_2 263300_2 99315_2 271509_2 2714
use strict;
use warnings;

my $line = qq{"229269_2,190594_2,94552_2,266076_2,269628_2,165328_2,99319_2,263339_2,263300_2,99315_2,271509_2,2714",A,1 the next line could look like 84545,X,2};

if ($line =~ /^"(.*?)"|^([^,]*)/) {
    my $column0 = $1 // $2;
    my @nums = split ',', $column0;

    print "@nums\n";
}

how to add 'item_qty' if the 'item_id' matches, and store the new result in an array?

With these it helps I think this is what you need . loop the array and set item_id as key to new array and check if already item_id is isset add the quantity with existing quantity like this .
code :
    <?php

    $arr = array ( 0 => array ( 'item_id' => 13 , 'item_qty' => 3 ), 
                  1 => array ( 'item_id' => 10 , 'item_qty' => 7 ),
                  2 => array ( 'item_id' => 13, 'item_qty' => 2 ), 
                  3 => array ( 'item_id' => 10 ,'item_qty' => 4 ), 
                  4 => array ( 'item_id' => 10 ,'item_qty' => 4 ));

    $new_array =array();

    foreach($arr as $key=>$row)
    {

       $new_array[$row['item_id']]=isset($new_array[$row['item_id']])? array('item_id'=>$row['item_id'],'item_qty'=>$row['item_qty']+$new_array[$row['item_id']]['item_qty']) : $row;   
    }

    echo "<pre>";
    print_r($new_array);

    ?>
    Array
    (
        [13] => Array
            (
                [item_id] => 13
                [item_qty] => 5
            )

        [10] => Array
            (
                [item_id] => 10
                [item_qty] => 15
            )

    )
        Array
        (
            [0] => Array
                (
                    [item_id] => 13
                    [item_qty] => 5
                )

            [1] => Array
                (
                    [item_id] => 10
                    [item_qty] => 15
                )

        )

Java store matches in array

With these it helps Since you keep re-compiling the same regex, the group number is going to stay the same. You can put it at different indexes of the array, though:
code :
final String mcontentURI[] = new String[count];
final Pattern p = Pattern.compile("src=\"(.*?)\"");
for (int i = 0; i < count; i++) {
    Matcher m = p.matcher(content_val); // Use different strings here
    if (m.find()) {
        mcontentURI[i] = m.group(1);
    }
}
final String mcontentURI[] = new String[count];
final Pattern p = Pattern.compile("src=\"(.*?)\"");
Matcher m = p.matcher(content_val);
int i = 0;
while (i < count && m.find()) {
    mcontentURI[i++] = m.group(1);
}

it helps some times I have my pattern like this
code :
string s = "ash1a";
string pattern = @"[^h1]";
string[] matches = Regex.Matches(s, pattern).OfType<Match>().Select(m => m.Value).ToArray();
