做这类型的搜索比较少,看懂题意花了半天 题意:给你个n*n的图,老鼠一次最远走k步,老鼠起初在(0,0),每次偷吃的东西必须比之前偷吃的要大. #include<iostream> #include<cstdio> using namespace std; #define N 110 int map[N][N],dp[N][N]; int n,k; int dir[][2]={{1,0},{0,1},{-1,0},{0,-1}}; int solve(int x,int y) {…

HDU 1078 FatMouse and Cheese ( DP, DFS) 题目大意 给定一个 n * n 的矩阵, 矩阵的每个格子里都有一个值. 每次水平或垂直可以走 [1, k] 步, 从 (0, 0) 点开始, 下一步的值必须比现在的值大. 问所能得到的最大值. 解题思路 一般的题目只允许 向下 或者 向右 走, 而这个题允许走四个方向, 所以状态转移方程为 dp(x, y) = dp(nextX, nextY) + arr(x, y); dp 代表在 x, y 的最大值. 由于 下一…
