The exception is because (into-array [0 1 -7 2 -1 -3 4 5 -10])
is not an array of longs, use long-array instead.
In the areduce, we also have to return ret after each computation, like so:
(defn aremove [pred ^longs ns]
(areduce ns i ret (long-array (alength ns))
(let [v (aget ns i)]
(when-not (pred v)
(aset ret i v))
ret)))
(seq (aremove pos? (long-array [0 1 -7 2 -1 -3 4 5 -10])))
;=> (0 0 -7 0 -1 -3 0 0 -10)
The next problem is all the zeroes. I don't know how to solve this problem
with arrays. :)
