Clojure - Splitting a vector

Question

If I have two arguments [[1 2] [3 4]] and [5 6], how can I get to [[1 5] [2 6] [3 5] [4 6]].

I thought I may have to use for so I tried,

(fo         


        

Answer 1

(mapcat #(map vector % [5 6]) [[1 2] [3 4]])

or using for:

(for [c [[1 2] [3 4]]
      p (map vector c [5 6])]
  p)
