What do you mean by 'n'?
Size of the final array? It's { scalar @final_array }, yes, that simple. )
Number of arrays to merge? Well, I guess they should be stored somewhere
anyhow. )
And if they're stored in some collection, like...
*my @collection_of_arrays = (*
* [1, 2, 3],*
* [4, 5, 6],*
* [7, 8, 9] *
*)*
... then again the number is the size of this collection. And it's pretty
easy to flatten this @collection, like this:
*my @flattened_collection = map { @$_ } @collection_of_arrays;*
*
*
You'd like to store arrays as separate variables instead - but don't know
their number at 'compilation' time? ) And this is practical task? )
Yes, this can be solved with soft references one way or another (*@result_array
= map { eval { '@array'.$_ } } 1..n*), but why you might ever need this, is
beyond me. )
