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 !
```
def pig_it(text):
    new_string = ""
    for each in text.split():
        if each == "?": 
            new_string += "? "
        elif each == "!":
            new_string += "! "
        else:    
            new_string += each[1:len(each)] + each[0] + "ay "
    a= len(new_string)    
    return new_string[0:a-1]

def pig_it(text):
    new_string = ""
    for each in text.split():
        if each == "?": 
            new_string += "? "
        elif each == "!":
            new_string += "! "
        else:    
            new_string += each[1:len(each)] + each[0] + "ay "
    a= len(new_string)    
    return new_string[0:a-1]
