input: Write a function called `find_match` that takes a user input string and searches it against a predefined list of strings to determine if there is any match. If a match is found, the function should print "String matches", otherwise it should print "String doesn't match". The function should use regular expressions for the search.
  
  assert find_match(["First","Second","Third"])==None
  assert find_match(["Apple","Banana","Cherry"])==None
  assert find_match(["Cat","Dog","Elephant"])==None
output: def find_match(user_input):
      import re
      predefined_list = ["First", "Second", "Third", "Apple", "Banana", "Cherry", "Cat", "Dog", "Elephant"]
      for item in predefined_list:
          if re.search(user_input, item):
              print("String matches")
              return
      print("String doesn't match")
