input: Write a python function that takes an integer list of even length and determines if it can be divided into two sublists of equal length, each containing unique elements. If the division is possible, return true; otherwise, return false.
  
  Examples:
  >>> nums = [1,1,2,2,3,4]
  true
  >>> nums = [1,1,1,1]
  false
  
  Constraints:
  1 <= nums.length <= 100
  nums.length must be even
  1 <= nums[i] <= 100
  
  from typing import List
  
  def can_be_divided(nums: List[int]) -> bool:
      # Your implementation here
output: def can_be_divided(nums: List[int]) -> bool:
      from collections import Counter
      counter = Counter(nums)
      if all(v <= 2 for v in counter.values()):
          return True
      return False
