You are given a two dimensional array containing arrays of integers as an argument. Take each column and return the integer elements in a one dimensional array.

Requirements

• Must return an array of integers
• Must account for inner arrays of all different sizes

Example #1

solve([
  [1, 2, 3],
  [4],
  [5, 6, 7, 8]
])
> [1,4,5,2,6,3,7,8]

Example #2

solve([
  [1, 2, 3, 4],
  [5, 6, 7, 8],
  [9, 10]
])
> [1,5,9,2,6,10,3,7,4,8]
