Dear Sirs,
Given this array:
my @array = qw ( A B C D E );
I want to enumerate all its possible ranges
throughout the elements. Such that it gives
the following desired answer, that look like this ( I manually crafted it):.
my $ans = [ 'A',
'B',
'C',
'D',
'E',
'AB',
'ABC',
'ABCD',
'ABCDE',
'BCD',
'BCDE',
'CD',
'CDE',
'DE' ];
Later, I also want to extend this
to deal with AoA as an input. But with
the same concept.
Is there an efficient way to achieve it?
I truly do not know how to go about it.
Really hope to hear from you again.
