 Need Help??

I'd normally use a slightly simpler version of JohnGG's splice approach. Something like

```my @arr = qw/1 2 3 4 5 6 7 8/;
while(my (\$x,\$y) = splice @arr,0,2) {
say "\$x => \$y";
}

Something I've needed in the past was to get two arrays (odds and evens). Grep can do this. You could combine them into a hash thus:

```my @arr = qw/1 2 3 4 5 6 7 8/;

my (\$j,\$i)=(0,0);
my (\$x,\$y) = ([grep { ++\$i % 2} @arr] , [grep {\$j++ % 2} @arr]);
my %hash;
@hash{@{\$x}}=@{\$y};

for(keys %hash) {
say "\$_ => \$hash{\$_}"
}
Gives us:
```1 => 2
3 => 4
7 => 8
5 => 6
Or you could iterate them (which is safer if some x may be undef)
```my @arr = qw/1 2 3 4 5 6 7 8/;
push @arr, undef;
push @arr, 9;

my (\$j,\$i)=(0,0);
my (\$x,\$y) = ([grep { ++\$i % 2} @arr] , [grep {\$j++ % 2} @arr]);
\$i=0;
for(@{\$x}){
say \$_ ." => " . \$y->[\$i++] if(\$_);
}
Obviously that doesn't scale to big arrays. I'm sure List::MoreUtils is always the better approach.

Title:
Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post, it's "PerlMonks-approved HTML":

• Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
• Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
• Read Where should I post X? if you're not absolutely sure you're posting in the right place.
• Posts may use any of the Perl Monks Approved HTML tags:
a, abbr, b, big, blockquote, br, caption, center, col, colgroup, dd, del, div, dl, dt, em, font, h1, h2, h3, h4, h5, h6, hr, i, ins, li, ol, p, pre, readmore, small, span, spoiler, strike, strong, sub, sup, table, tbody, td, tfoot, th, thead, tr, tt, u, ul, wbr
• You may need to use entities for some characters, as follows. (Exception: Within code tags, you can put the characters literally.)
 For: Use: & & < < > > [ [ ] ]
• Link using PerlMonks shortcuts! What shortcuts can I use for linking?
