You will be given a definition of a task first, then an example. Follow the example to solve a new instance of the task.
In this task you will be given a list of numbers and you should remove all duplicates in the list. If every number is repeated in the list an empty list should be returned. Your list should be numbers inside brackets, just like the given list.
