input: Write a function in Python to print out an array backwards. The function should take an array `arr` as input and print each element of the array in reverse order.
  assert print_reverse_array([1, 2, 3, 4, 5])== [5, 4, 3, 2, 1]
  assert print_reverse_array([10, 20, 30])== [30, 20, 10]
  assert print_reverse_array([])== []
output: def print_reverse_array(arr):
      for i in range(len(arr)-1, -1, -1):
          print(arr[i])
