Move the first letter of each word to the end of it, then add "ay" to the end of the word. Leave punctuation marks untouched.

## Examples

```python
pig_it('Pig latin is cool') # igPay atinlay siay oolcay
pig_it('Hello world !')     # elloHay orldway !
```
```C++
pig_it("Pig latin is cool");   // igPay atinlay siay oolcay
pig_it("Hello world !");       // elloHay orldway
```
```Java
PigLatin.pigIt('Pig latin is cool'); // igPay atinlay siay oolcay
PigLatin.pigIt('Hello world !');     // elloHay orldway !
```
