给你一对数a,b，你可以任意使用(a,b), (a,-b), (-a,b), (-a,-b), (b,a), (b,-a), (-b,a), (-b,-a)这些向量，问你能不能拼出另一个向量(x,y)。

说明：这里的拼就是使得你选出的向量之和为(x,y)

 

输入格式

第一行数组组数t，(t<=50000)

接下来t行每行四个整数a,b,x,y  (-2*10⁹<=a,b,x,y<=2*10⁹)

输出格式

 

t行每行为Y或者为N，分别表示可以拼出来，不能拼出来

3
2 1 3 3
1 1 0 1
1 0 -2 3

Y
N
Y

数据范围与约定

 



样例解释：



第一组：(2,1)+(1,2)=(3,3)



第三组：(-1,0)+(-1,0)+(0,1)+(0,1)+(0,1)=(-2,3)
