Hello everyone,
I'm struggling with some kind of array construction task, which should
be fairly easy in J, but I found this a hard nut to crack. Say, I have
three arrays:
A =: 'a';'b'
B =: 'c';'d'
C =: 'e';'f'
What I want to construct is the following array:
D =: 8 3 $ <"0 'aceacfadeadfbcebcfbdebdf'
I'd very much appreciate any hints on how to approach this problem.
Kind regards,
Thomas
