/* HDU1035 题意： 给定一个字符矩阵，NSWE分别代表向上，下，左，右前进 模拟搜索，判断： 若能走出字符矩阵，则Yes，输出步数 若走不出矩阵，那么必定有圈存在，必定在矩阵中存在一个点会访问第二次

做水题找感觉，一次AC水过的#include #include usingnamespacestd; introw,column,start; intmap[11][11]; chardir[11][11]; intstep; boolflag; intbefore; voidDFS(intx,inty) { if(map[x][y]!=0) { flag=true; before=map[

mp[r][c][0]保存地图上(r,c)的方向如下                  N(8)       W(4)               E(6)                   S(2)mp[r][c][1]保存点(r,c)被经过的次数 当第三次遇到(r,c)是不再继续否则mp[r][c][1]++  #include usingnamespacestd; intmain() {

 这是我在HDU上解决的第一道独立完成的dfs，故此一记！这题WA了两次：1、在写dfs()函数时将递归出口写成了if(r==0||r==10||c==0||c==10)。试想怎么可能是10呢？要根据输入的行列来确定出口哇！2、把记录遍历点的nodeppp[50]开成50，试想行列最大都为10，那么走过的点很可能会超过50呀！那么回溯是就会出错啦！详见代码注释：#include usingnam

HDU1035这道题的处理方法是把待处理的字符数组边界设为空格作为出口的标志，另设一个记录所走步数的数组steps，但是这个题目分两个走法，其一没有重复的路径，遇到空格后直接输出的步数，用mark=0标记
