Yep, this was new to me as well, as evidenced by my original awkward |"0 1
construction.

box a command to show how that flow
works, but I don't remember it. Or maybe that's not it at all and I'm just
confused.

So I tried to write code to solve the general case of Project Euler problem
1. The problem given is to find the sum of all the positive integers less
than 1000 that are divisible by 3 or 5. Obviously the specific case is
highly optimizable. But I wanted to solve the general, with any number of

I'm curious how fast J is to write for someone who knows what they're
doing?
In AdventOfCode only the first 100 submissions make the leaderboard, so
speed is a premium. I dabble in J, but I'm *far* more comfortable in
LiveCode, and that's what I use for AdventOfCode, although I sometimes go
back

Thanks -- in the end I understood it well enough to see that it had a bug,
and create a correct alternative, so I'm feeling pretty good about it now.

I get:
inc 'a'
b
inc 'z'
ba
inc 'y'
z
And my grasp of J isn't strong enough to figure out why. I came up with
this alternative that seems to work:
inc =: ((26&|)@>:)&.(alpha&i.)
Perhaps that could

That's a lot to dig through, thanks!

Is that because @ binds more tightly than / or am I thinking in C terms?
As an aside, I love how J makes me think *completely* differently about
programming. I have developer friends who think they're multi-lin

Thanks! I definitely tend to throw parentheses at the problem when a train
doesn't work the way I expect.
And looking at everyone else's solutions, I realized that the weakness of
my understanding of i. was making my solution

F =: #-(+:@(+/@('('&i.)))
If S is the string from the site, then
F S
returns the ending floor (the first part of the challenge).
Any suggestions on improving the syntax are welcome, I only dabble in J.
thx
