input: Write a function to optimize the given Python program by simplifying the printing process of the elements in a list. The function should return the optimized version of the program as a string.
  assert optimize_program(["1", "2", "3", "4", "5", "6"])=='numbers = ["1", "2", "3", "4", "5", "6"]\nprint(*numbers, sep="\\n")'
  assert optimize_program([""])=='numbers = [""]\nprint(*numbers, sep="\\n")'
  assert optimize_program([])=='numbers = []\nprint(*numbers, sep="\\n")'
output: def optimize_program(numbers):
      return f'numbers = {numbers}\nprint(*numbers, sep="\\n")'
