Question: you have an array of integers and an array of sort order. You have to sort input array according
to that sort order. Those numbers don't belongs to order list will sort ascending order and will add at
the last of the result.
Example:
  Input: [2, 3, 8, 4, 3, 5, 2, 7, 6, 2, 3, 5, 4, 1]
  Order: [5, 2, 3]
