input: Write a function to print a Python array from the end to the beginning. The function should take a list as input and print each element in the reverse order. If the array is empty, it should print nothing.
  
  def printArrayReverse(arr): 
      for i in range(len(arr) - 1, -1, -1): 
          print(arr[i], end = " ")
  
  assert printArrayReverse([1, 2, 3, 4, 5])
  assert printArrayReverse([])
output: def printArrayReverse(arr): 
      for i in range(len(arr) - 1, -1, -1): 
          print(arr[i], end = " ")
