C++ :

#include <iostream>
using namespace std;

int main() {
	int X, Y; cin >> X >> Y;
	if (X <= 8 && Y <= 8) cout << "Yay!" << endl;
	else cout << ":(" << endl;
	return 0;
}

Python :

# coding=utf-8
def getint():
    return [int(i) for i in input().split()]
def get():
    return int(input())
def S():
    for test in range(int(input())):
        solve()
def solve():
    n=get()



a,b=getint()
if a<=8 and b<=8:
    print("Yay!")
else:
    print(":(")
