题意:在一个地图里逃亡,2是起点,3是终点,1是路,0是墙,逃亡者携带一个炸弹,6分钟就会炸,要在6分钟前到达4可以重制时间,问是否能逃亡,若能则输出最小值 我的思路:bfs在5步内是否存在3,存在则输出退出.记录到达每一点剩余时间,如果再次到达某点的剩余时间大于原剩余时间则更新,加入队列. #include <iostream> #include <cstring> #include <queue> using namespace std; ; int map[M][…

题目大意: 在迷宫中有一个炸弹,过六个单位时间就会爆炸,要你求一个起点到迷宫的终点的最短距离,迷宫中有时间重置器,当你走到这个格子,炸弹的爆炸时间重新置为0,迷宫中标识为墙壁的格子不能走,到达任意一个格子时,炸弹计数器为0时,则失败. 求逃出迷宫最短距离,bfs. 但是有两个限制条件,1.求最短,2.炸弹时间不小于1(等于零不OK). 解锁bfs新姿势.(赞! #include<iostream> #include<cstring> #include<queue> #d…
