      for i in range(len(arr) - 1, -1, -1): 
          print(arr[i], end = " ")
  
  assert printArrayReverse([1, 2, 3, 4, 5])==None
  assert printArrayReverse([10, 20, 30, 40])==None
  assert printArrayReverse([])==None
output: def printArrayReverse(arr): 
      for i in range(len(arr) - 1, -1, -1): 
          print(arr[i], end = " ")
