Problem of the Day
A new programming or logic puzzle every Mon-Fri

Today's problem will be a bit easier than yesterday's problem. Our goal for today is to see how deep we can go. Given an n-dimensional, integer array, combine all arrays in to one single array.

[
  [
    [7,5,3],[52,2]
  ],
  [
    [45,467]
  ]
]

[7,5,3,52,2,45,467]

  (defn my-flatten [coll]
    (remove coll?
            (tree-seq coll? identity coll)))
  

  > (my-flatten [[[7 5 3] [52 2]] [[45 467]]])
  (7 5 3 52 2 45 467)

  Javascript:

  var ar = [ [ [7,5,3],[52,2] ], [ [45,467] ] ];

  var result = [].concat.apply(ar);
