PROGRAMMING:String test 02
Enter a string (less than 20 in length) and split it into two strings from the middle
For example, 12345678 is divided into 1234 and 5678
If the input string has an odd number of characters, the two strings after segmentation are not equal in length, and the short string comes first, for example
123456789 is divided into 1234 and 56789
###Input format:
Enter a string less than 20 in length
###Output format:
Output two strings separated by commas. If the input string has an odd number of characters, the two strings are not equal in length, and the short string comes first
###Input example:

```in
one hundred and twenty-three million four hundred and fifty-six thousand seven hundred and eighty-nine
```
###Output example:
