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,…

http://acm.hdu.edu.cn/showproblem.php?pid=5015 由于是个二维的递推式,当时没有想到能够这样构造矩阵.从列上看,当前这一列都是由前一列递推得到.依据这一点来构造矩阵.令b[i]代表第i列,是一个(n+2)*1的矩阵,即b[1] = [1,233......],之所以在加了两行,是要从前一个矩阵b[i-1]得到b[i]中的第二个数2333...,再构造一个转换矩阵a,它是一个(n+2)*(n+2)的矩阵,那么a^(m-1) * b就是第m列. /* a矩…
