E - Tiling_easy version 题目大意: 有一个大小是 2 x n 的网格,现在需要用2种规格的骨牌铺满,骨牌规格分别是 2 x 1 和 2 x 2,请计算一共有多少种铺设的方法. 一个简单的dp问题: dp[i+2]=dp[i+1]+2*dp[i]; 初始条件:dp[1]=1;dp[2]=3; 一开始没考虑清楚,把递推关系写成dp[i+2]=3*dp[i]; 解释一下dp[i+2]=dp[i+1]+2*dp[i] dp[i+2]相对于dp[i]正好多一个2x2的正方形,当前…
Tiling_easy version 思路:关于dp这种东西,有一点必须要想明白,就是状态与状态之间的转换关系,就比如说要求5个骨牌的方案数,因为有两种骨牌,那么可以用dp[3]+两个横着的骨牌或者一个2*2的骨牌,或者是dp[4]+一个竖着的1*2骨牌来构成,那么递推的公式就是dp[5]=dp[3]*2+dp[4] 代码: // Created by CAD on 2019/10/10. #include <bits/stdc++.h> using namespace std; int d…
