/* I must say that it is a tricky quiz, there a girl named who

Sadia loves even numbers. She will give us two int numbers and if the

average of that two int is even she will be happy. Otherwise,

she will not be happy

But, the twist here is we will have to take t as int which

will decide how many times the program will run.

For example, if we give t =3 then the program will run for 3 test

case*/

int main(){

    int  t;

    scanf("%d",&t);// t here denote test case.if t=3,the programm

    // will run for 3 times

    while(t--)

    {

    int X1,Y1,avg;

    scanf("%d%d",&X1,&Y1);

    avg =(X1+Y1)/2;

    if(avg%2==0)

    {

        printf("Sadia will be happy.\n");

    }

   else

   {

       printf("Oops!\n");

   }

    }

    return 0;
