A robot has to patrol around a rectangular area which is in a form of m x n grid (m rows and ncolumns). The rows are labeled from 1 to m. The columns are labeled from 1 to n. A cell (i, j)denotes the cell in row i and column j in the grid. At each st…
这道题运用的知识点是求最短路的算法.一种方法是利用BFS来求最短路. 需要注意的是,我们要用一个三维数组来表示此状态是否访问过,而不是三维数组.因为相同的坐标可以通过不同的穿墙方式到达. #include <bits/stdc++.h> using namespace std; struct Node{ int r; int c; int g; int cnt; Node(int r,int c,int g,int cnt):r(r),c(c),g(g),cnt(cnt){} }; ][][]…
非常适合A*的一道题. 比普通的迷宫问题加一个信息k表示当前穿过的障碍物的数量. #include<cstdio> #include<cstring> #include<queue> using namespace std; ; int m,n,k; int C[MAX][MAX][MAX]; int G[MAX][MAX]; int tarx,tary; struct node { int g,h; int x,y;//对于本题 x+y 越大距离终点越近 int k;…

基本思路就是Bfs: 本题的一个关键就是如何判段状态重复. 1.如果将状态用一个int型数组表示,即假设为int state[17],state[0]代表机器人的位置,从1到M从小到大表示障碍物的位置.那么如果直接用STL中的set是会超时的,但如果自己建立一个hash方法,像这样: int getKey(State& s) { long long v = 0; for(int i=0; i<=M; ++i ) { v = v * 10 + s[i]; } return v % hashSi…
Robot Instructions You have a robot standing on the origin of x axis. The robot will be given some instructions. Your task is to predict its position after executing all the instructions. LEFT: move one unit left (decrease p by 1, where p is the p…
