I wrote a function as:
(defn repeated-seq
[f start]
(let [coll (f start)]
(concat coll (lazy-seq (repeated-seq f (last coll))))))
it is OK when I call it with:
(repeated-seq #(range % 5) 0)
the elements are: 0 1 2 3 4 4 5 6 7 8 8 ...
However, I want to get rid of the duplicated index element (4, 8 etc),
e.g.
To produce 0 1 2 3 4 5 6 7 8 9
But when I insert a rest into lazy-seq, the function just hung up.
How can I make this happen?
Thanks.
