Problem Statement

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 :(.

Constraints

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

Sample Input 1

180

Sample Output 1

Yay!

For $N=180$, the tax-included price is $\lfloor 180 \times 1.08 \rfloor = 194$ yen, which is lower than the list price of $206$ yen.

Sample Input 2

200

Sample Output 2

:(

Sample Input 3

191

Sample Output 3

so-so

In this case, the tax-included price is exactly equal to the list price of $206$ yen.
