It is the final day of La Liga. Chef has a certain criteria for assessing football matches.  
In particular, he only likes a match if:
The match ends in a draw, and, 
At least one goal has been scored by either team. 

Given the goals scored by both the teams as X and Y respectively, determine whether Chef will like the match or not.

------ Input Format ------ 

- The first line of input will contain a single integer T, denoting the number of test cases. The description of T test cases follows.
- Each test case consists of a single line of input containing two space-separated integers X and Y — the goals scored by each team.

------ Output Format ------ 

For each test case, output \texttt{YES} if Chef will like the match, else output \texttt{NO}. 

You may print each character of the string in uppercase or lowercase (for example, the strings \texttt{YeS}, \texttt{yEs}, \texttt{yes} and \texttt{YES} will all be treated as identical).

------ Constraints ------ 

$1 ≤ T ≤ 100$
$0 ≤ X, Y ≤ 9$

----- Sample Input 1 ------ 
4
1 1
0 1
0 0
2 2

----- Sample Output 1 ------ 
YES
NO
NO
YES
----- explanation 1 ------ 
Test case $1$: It is a draw in which both teams have scored a goal, Chef will like this match.

Test case $2$: The game is not a draw. Hence, Chef will not like this match.

Test case $3$: Neither team scored a goal, so Chef will not like this match.

Test case $4$: It is a draw in which both teams scored $2$ goals each. Chef will like this match.
