### Instructions
|
||
|
|
|
||
|
|
Write a program that checks if a number up to a given number is an odd or even number.
|
||
|
|
The number will be between `0` and `100`.
|
||
|
|
|
||
|
|
- If the number is `odd` then it prints `ping` as in the example below.
|
||
|
|
- If the number is `even` then it prints `pong`.
|
||
|
|
- If the number of arguments is invalid then do nothing.
