According to him, there are six integers a 1.a2,a3,b1,b2,b3 whose values are fixed and the number written in the square (ij) is equal to aitbi. You are required to determine whether Bob is correct or not. Input format The first line contains an integer T denoting the number of test cases. Next three lines contain three space-separated integers Cil. Ci2, and Ci3 denoting the ith row of grid C. Output format For each test case, print YES if Bob's statement is correct.
