[Jprogramming] Is there a way to distinguish input 1 from 01 ?

[Piet de Jong]

Thanks to everyone!
I now understand things better.
That’s one of the things I like about J.
It forces you unravel the confronted computing task  in a “deep” manner.
Not just hack a solution (although you can if you want)
The “unravelling” is great feedback for my understanding of the subject matter.
(In this, my case, it was Quantum Mechanics/Computing — trying to come to grips with “kets” and the various operations associated therewith).

Again thanks to everyone who gave feedback.
