Mr. Pr and Ms. Ad are at $a$ and $b$ respectively on an infinite number line. Mr. Pr wants to meet Ms. Ad.

Mr. Pr can choose to move  $c$ or $d$ units in 1 second. If Mr. Pr moves $c$ units then Ms. Ad will move $d$ units and vice versa. (Both of them always moved in positive x-direction)

You have to determine if Mr. Pr can meet with Ms. Ad after some integral amount of time, given that Mr. Pr chooses optimally. Note that meeting after a fractional amount of time does not count.

------ Input: ------

First line will contain $T$, number of testcases. Then the testcases follow. 
Each testcase contains four space separated integers, $a$, $b$, $c$, and $d$.

------ Output: ------
For each test case, output a single line containing "YES" if Mr. Pr meets with Ms. Ad, otherwise "NO".

------ Constraints  ------
$1 ≤ T ≤ 10^{5}$
$1 ≤ a,b,c,d ≤ 10^{9}$

----- Sample Input 1 ------ 
2
3 4 1 2
10 20 3 7
----- Sample Output 1 ------ 
YES
NO
----- explanation 1 ------ 
In the first test case, Mr. Pr will move 2 units in the first second and Ms. Ad moves 1 unit simultaneously and they meet. 

In the second test case, it is impossible to meet (fractional time is not allowed).
