How to smooth seq containing seq vectors

Question

I have seq in this format -

(([2 3 4] [7 6 8]) (["hh" 5] [9 8]))

I want to smooth it so that its seq vectors instead of seq from a vector vector. How can I do it?

Also smooths it completely, I only want to smooth it one level up to - ([2 3 4] [7 6 8] ["hh" 5] [9 8])

Answer 1

Try concat :

 (apply concat seq) 

Answer 2

 (reduce (fn[hv] (reduce (fn[se] (conj se)) hv)) [] [[[2 3 4] [7 6 8]] [["hh" 5] [9 8]]])
