Hello guys.
I have just started learning J and got some problems with TACIT form of
thinking...
Thus I'll be asking some silly question for first time :)
So the question is:
I have a string of chars. I need to insert space between each two characters.
Sounds like a
simple task, but I can't figure out how to compose a corresponding verb.
Surely, I defined an explicit function solving this problem. It looks like
join =: 4 : 0
x., ' ', y.
)
now this works as
join / 'Sassa'
S a s s a
It works well but it is a still imperative. And I want to learn to think in
functionals.
I will be very joyful if you help me.
Thanks a lot, and sorry if made some spam :)
