The consumption tax rate in the Republic of AtCoder is $8$ percent.

An energy drink shop in this country sells one can of energy drink for $N$ yen (Japanese currency) without tax.

Including tax, it will be $\lfloor 1.08 \times N \rfloor$ yen, where $\lfloor x \rfloor$ denotes the greatest integer not exceeding $x$ for a real number $x$.

If this tax-included price is lower than the list price of $206$ yen, print `Yay!`

; if it is equal to the list price, print `so-so`

; if it is higher than the list price, print `:(`

.

- $1 \le N \le 300$
- $N$ is an integer.

Input is given from Standard Input in the following format:
