For example, $A_1=(3,4,4)$, $A_2=(4,3,0)$, $A_3=(2,3,2)$, $A_4=(9,10,6)$ has a non-negative solution because $A_1+A_2+A_3 = A_4$. Input The first line contains an integer $T$ $(1 \leq T \leq 1000)$, representing the number of test cases. Each test case consists of a single line containing $12$ integers in $a_{11}, a_{12}, a_{13}, a_{21}, a_{22}, a_{23}, a_{31}, a_{32}, a_{33}, a_{41}, a_{42}, a_{43}(0 \leq a_{ij} \leq 10^4,1\leq i \leq 4,1\leq j \leq 3)$, representing the components of the four three-dimensional vectors $A_1, A_2, A_3, A_4$. Output For each test case, output a single line containing either "YES" or "NO", indicating whether a non-negative solution exists. If a non-negative solution exists, output "YES"; otherwise, output "NO". Sample Input
