Problem

Hackerman wants to know who is the better player between Bob and Alice with the help of a game.

The game proceeds as follows:

• First, Alice throws a die and gets the number $A$
• Then, Bob throws a die and gets the number $B$
• Alice wins the game if the sum on the dice is a prime number; and Bob wins otherwise.

Given $A$ and $B$, determine who wins the game.

Input Format

• The first line of input will contain a single integer $T$, denoting the number of test cases.
• The first and only line of each test case contains two space-separated integers $A$ and $B$.

Output Format

For each test case, output on a new line the winner of the game: Alice or Bob.

Each letter of the output may be printed in either uppercase or lowercase, i.e, Alice, ALICE, AlIce and aLIcE will all be considered equivalent.

Explanation:

Test case $1$: $A = 2$ and $B = 1$. Their sum is $2+1 = 3$ which is a prime number, so Alice wins.

Test case $2$: $A = 1$ and $B = 1$. Their sum is $1+1 = 2$ which is a prime number, so Alice wins.

Test case $3$: $A = 2$ and $B = 2$. Their sum is $2 + 2 = 4$ which is not a prime number, so Bob wins.
