how to remove a particular occurances from sequence clojure

Question

If I have sequence

[1 1 1 1 3 2 4 1]

how can I remove a particular number from that sequence? For example

(remove [1 1 1 1 3 2 4 1] 1) -> [3 2 4]

You can use a set as a predicate to remove, because sets can be called as functions.

(remove #{1} [1 1 1 1 3 2 4 1])
=> (3 2 4)

wrap that in (vec ..) if you need the result to be a vector.

The bonus of that approach is that you could remove many arbitrary values by sticking them in the set. If it's just one, this of course works too:

(remove #(= 1 %) [1 1 1 1 3 2 4 1])
