## rot-arg-n |
||||||
|
|
||||||
|
### 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. |
||||||
|
|
||||||
|
