input: Write a function to read a list of integers and print its elements in reversed order. If the list is empty, print an empty list.
  assert print_reversed_order([1, 3, 6, 8, 10])==None
  assert print_reversed_order([])==None
  Output should be:
  [10, 8, 6, 3, 1]
  []
output: def print_reversed_order(lst):
      print(lst[::-1])
