Re^2: Sorting array with multiple values per keys

Thanks for the great reply, guys. I chose to use this as a solution:


my @Array = (
    [1, 5],
    [6, 2],
    [3, 4],
    [3, 9],
    [8, 1],
);

@Array = sort {
    $a->[0] <=> $b->[0] or $b->[1] <=> $a->[1]
} @Array;

It works great but how do I call the first element of the first element in the @Array now? Something like @Array[0]->[0] ? And can I still use foreach operators now? Like:


foreach @Elements (@Array) { 
   print @Elements[0]."x".@Elements[1];
}

Like I already said, `@Array[0]` is inappropriate and produces a warning. Use `$Array[0]->[0]` or `$Array[0][0]` for short.	[reply] [d/l] [select]

`foreach $Elements (@Array) { print $Elements->[0] . 'x' . $Elements->[1]; }` [download] Loop variables in foreach loops must be scalars, but scalars can be array references.	[reply] [d/l]
