# Description:

 Find the longest successive exclamation marks and question marks combination in the string. A successive exclamation marks and question marks combination must contains two part: a substring of "!" and a substring "?", they are adjacent. 
 
 If more than one result are found, return the one which at left side; If no such a combination found, return `""`.

# Examples

```
find("!!") === ""
find("!??") === "!??"
find("!?!!") === "?!!"
find("!!???!????") === "!!???"
find("!!???!?????") === "!?????"
find("!????!!!?") === "????!!!" 
find("!?!!??!!!?") === "??!!!"
```
