### Instructions
|
||
|
|
|
||
|
|
Write a program that takes arguments from the command line and rotates them by the number in the first argument.
|
||
|
|
- If the number of arguments is less than 3 print (`'\n'`)
|
||
|
|
- If the first argument is not a number, the program should print `"Error\n"`
|
||
|
|
- If the first argument is negative, the program should print `"Error\n"`
|
||
|
|
- If the first argument is zero, the program should print the original arguments
|
||
|
|
- Prints the rotated arguments with a space between each argument and a newline at the end.
