Neither makes much sense.
And the map based one is actually even more memory hungry.
@out_array_bin = ();
or
undef @out_array_bin;
will clear the array completely and will be much quicker.
The problem with the for(){} is that it doesn't get rid of the whole
array, just the values of the elements. So you end up with a huge
array containing empty strings. Which will take up quite some memory.
The map{} is even worse because instead of "clearing" the array "in
place" it creates a new huge array containing the empty strings. So
at one point you have two huge arrays. One containing the data and
the other containnig the empty strings :-(
