93. Consider two arrays A and B of shape (8,3) and (2,2). How to find rows of A that contain elements of each row of B regardless of the order of the elements in B? (★★★) 
use strict;
use warnings; 
use PDL;

my $A = floor(random(3,8) * 6);
my $B = floor(random(2,2) * 6);

my $C = $A->in($B->slice(',0'))->sumover * $A->in($B->slice(',1'))->su
+mover ;
my $rows = which($C > 0);
print $rows;
