Multiple test cases, the first line contains an integer $T$(no more than $10000$), indicating the number of cases. Each test case contains twelve integers $x1,y1,z1,x2,y2,z2,x3,y3,z3,x4,y4,z4,\left|x \right|,\left|y \right|, \left|z \right| \leq 100000$,representing coordinate of four points. Any pair of points are distinct.

For each case, the output should occupies exactly one line. The output format is Case #$x$: $ans$, here $x$ is the data number begins at $1$, if your answer is yes,$ans$ is Yes, otherwise $ans$ is No.
