HDU 6330--Visual Cube(构造，计算)

Visual Cube

• 将这个立方体分块，分成上中下三个部分，利用长宽高计算行列，最后输出即可。
  
  每个部分都分成奇偶行来输出，总共有\(2*(b+c)+1\)行，共\(2*(a+b)+1\)列。设当前行为\(i\),划分方式:当行数小于等于\(2*b\)时，在上部，当$i > (2 * b) $ && \(i<=2*c+1\)时，在中部,其余在下部。这样的划分可以应对绝大部分情况，但是对于上部有一中情况是不包括的，当$b>c $时，如果继续之前的划分，那么在头部判定之后，它依然符合下部的判定，所以这时也被当作下部输出，这不是预期的结果，所以在上部加上额外的判定。
