What's so hard about Day 12? It's just

    +/'{x:".",x;H:(-1+;1+i-)@'+|\m*i:!#m:x=\:"#."
     R:(x=x)({[h;d;x;y;z](z#0),+\(((-z)_~"#"=x)&z_d>z)*(*y),(-z+1)_y-0^y h}. H)[x]/y
     (*|R)-R@*|0,&1_*+m}.''1({("?"/:5#,x;,/5#,y)}.')\@[;1;.:]'" "\:'0:`:i/12.txt

This is what programming languages looked like to me before I learned programming

I'm doing this year in K2 (after a long hiatus from K). Is there a K4/5 binary? ATW gave me a K2 binary, but I miss some of the K4 and later functionality):

I don't know if there's a specific k4 binary but you can run k4 through the q binary.

Any idea how close that is to valid J code?

[7thaccount]

My limited understanding is that K and J are very different, despite both being in the same language family. I found K a lot easier to grasp when I was playing with both languages years ago.

Is this Q? or k?

[rak1507]

It's k4, the underlying language behind Q. With slight modifications it also runs in ngn/k which is FOSS.

Looks like K to me!
