题目描述 有一个m行n列的矩阵,用1*2的骨牌(可横放或竖放)完全覆盖,骨牌不能重叠,有多少种不同的覆盖的方法? 你只需要求出覆盖方法总数mod p的值即可. 输入格式 三个整数数n,m,p,m<=5,p<=10000,n<=10000 输出格式 一个整数:总数模p的结果 不难想到可以用状压来做这题.设dp(i,j)表示第i列放置情况为j的二进制表示,其中j的第k位为1时表示这玩意是一块竖着的骨牌的上半部分,为0则是其余的情况.我们考虑一下dp(i,j)可以由哪些状态转移而来. 设上一行…

题目:id=2411" target="_blank">poj 2411 Mondriaan's Dream 题意:给出一个n*m的矩阵,让你用1*2的矩阵铺满,然后问你最多由多少种不同的方案. 分析:这是一个比較经典的题目.网上各种牛B写法一大堆.题解也是 我们能够定义状态:dp[i][st]:在第 i 行状态为 st 的时候的最慷慨案数. 然后转移方程:dp[i][st] = sum (dp[i-1][ss]) 即全部的当前行都是由上一行合法的状态转移而来. 而状态…
