Hello everyone,

I have a hash, that could look like this:

 

my %hash = (
1  => 'hello', 
2  => 'wizeguy', 
4  => 'zoom', 
5  => 'foo', 
24 => 'grr', 
);

I want to be working on the value of key number five, but I'll need the value of the previous and next keys (when sorted in numnerical order), in other words, if I'm working on $hash{2} I need the value of $hash{1} and $hash{4}

This seems really tricky to me, especially when the key values skip numbers and/or you're at the end of the sorted hash, like $hash{24} and $hash{1}.

It makes sense that I should first sort the keys in numeric order using an array to hold the keys but after that I'm stumped, all my loops aren't working,

Anyone want to help?
