TETRAHED - Point in tetrahedron |
There're given 5 points in 3D coordinates (integers 0 <= x, y, z < 100). Their order is arbitrary. 4 of them are the vertices of a tetrahedron whose edges can be of different size. One is lying in this tetrahedron. Find its index (1-5) in the array of points.
Input
In the first line the number T (T<1000) of test cases.
Then for each test case 5 lines with the space separated x-, y- and z-coordinates of the 5 points.
Output
For each test case a line with the index of that point which is lying in the tetrahedron formed of the 4 other points.
Example
Input: 1
5 72 66
92 23 68
60 60 49
74 78 33
67 76 27 Output: 3

@HWK, my fault. I forgot to put "\n"'s to the output. |

@ZiYuan: You didn't blunder. Only add whitespace to the output. ;-) I changed the problem description to clarify this. Last edit: 2011-10-02 16:28:56 |

@HWK, could you tell me the test case where I blundered? The submission ID is 5762600 or 5762625. Thank you~ Last edit: 2011-10-02 08:32:37 |

@Nelson González Peñate (UCI-01): E.g. 5 75 19 79 94 66 35 79 38 87 53 97 64 84 40 => 3, not 5. |
