    Given a list phoneNumbers, your task is to find the duplicate telephone number in the list.

    result = [
    "310-1010:2", ---> "3-10-10-10" and "310-GINO"
    "487-3279:4", ---> "4873279", "ITS-EASY", "-4-8-7-3-2-7-9-" and "487-3279"
    "888-4567:3"] ---> "888-4567", "888-GLOP" and "TUT-GLOP"
    

    Where is the another 3 Duplicate Phone Numbers? I think the others are not Duplicate Phone Numbers. Do you think so?
