input: Write a function to optimize the given Python program by modifying the way the numbers are printed. The function should take a list of numbers as input and return the same list but with the numbers printed in a more efficient manner.
  assert optimize_program([1, 2, 3, 4, 5, 6])==[1, 2, 3, 4, 5, 6]
  assert optimize_program([10, 20, 30])==[10, 20, 30]
  assert optimize_program([])==[]
output: def optimize_program(numbers):
      return numbers
