So I've been trying to do the 19th exercise, the top-left to bottom-right line one, and while trying to do something clever with ¦ (having hit 8 bytes with twoseparate more straightforward approaches) I realized that I don't really know how to use it at all
(got one of them down to 7 actually, but still two bytes over par)
@UnrelatedString It's not too bad of a quick to get the hang of. Basically, it takes an atom, a list and a list of indices, and applies the atom to the values in the list at those indices
So H[1,2,3]¦ would halve the first three elements of the input list
Huh, it is working fine now that I'm trying it on lists, so I guess the problem was just that I was trying to use it on an integer and it didn't rangify properly
