int main() {
    int a, b;
    char ch;
    while((ch = getchar()) != '=')
    {
        ;

    cin >> a;
    while((ch = getchar()) != '=')
    {
        ;
    }
    cin >> b;
    a = a ^ b;
    b = a ^ b;
    a = a ^ b;
    cout << "a=" << a << ",b=" << b;

    return 0;
}
// 64 位输出请用 printf("%lld")
