Problem 60186. Remove Unique Elements

Difficulty:
(444)
Rate
Given a list of integers, we want to keep only the non-unique elements in this list. To do this, we need to remove all the unique elements (elements that appear only once). The resulting list, denoted by C, must not change the order of the original list. Complete the function dupe(L) which returns the new list C.
Example:
  • If L=[1,2,3,1,3] then C=[1,3,1,3]
  • If L=[1,2,3,4,5] then C=[]
  • If L=[5,5,5] then C=[5,5,5]
  • If L=[10,9,10,10,9,8] then C=[10,9,10,10,9]
