检查给定向量是否处于平衡状态

给定三个向量的x，y和z坐标，任务是检查它们是否处于平衡状态。
例子：

Input: x1 = -2, y1 = 1, z1 = 0, x2 = 5, y2 = 0, z2 = 5, x3 = -3, y3 = -1, z3 = -5 
Output: The vectors are at equilibrium.
Input: x1 = 2, y1 = -17, z1 = 0, x2 = 5, y2 = 1, z2 = -5, x3 = 4, y3 = 2, z3 = -4 
Output: The vectors are not at equilibrium.

当三个向量处于平衡状态时

方法：当三个向量的结果为空向量时，三个向量处于平衡状态，即它没有大小和方向。三个向量的结果等于向量的向量和。当∑x = 0，∑y = 0且∑ z = 0时，结果向量为Null。因此，可以说，当所述条件满足时，向量处于平衡状态，否则不平衡。
