Chef has two integers A and B (A ≤ B). 

Chef can choose any non-negative integer X and add them to both A and B. Find whether it is possible to make A a [divisor] of B.

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

- The first line of input will contain a single integer T, denoting the number of test cases.
- Each test case consists of two integers A and B.

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

For each test case, output YES if it is possible to make A a factor of B, NO otherwise.

You can print each character of the string in uppercase or lowercase. For example, the strings Yes, YES, yes, and yEs, are all considered identical.

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

$1 ≤ T ≤ 10^{5}$
$1 ≤ A ≤ B ≤ 10^{9}$

----- Sample Input 1 ------ 
3
3 6
4 14
9 10

----- Sample Output 1 ------ 
YES
YES
NO

----- explanation 1 ------ 
Test case $1$: We can choose $X = 0$ and add them to $3$ and $6$. Thus, $3$ is a factor of $6$.

Test case $2$: We can choose $X = 1$ and add them to $4$ and $14$. Thus, $4+1 = 5$ is a factor of $14+1 = 15$.

Test case $3$: There is no possible value of $X$ to add such that $A$ becomes a factor of $B$.
