洛谷P3654 First Step题解

题目传送门这是一道暴力枚举。  大致题意:R行C列的棋盘要放下长度为K的线段,“#”表示无法放置,问有多少种放置方法。直接贴代码:#includeusingnamespacestd;intmain(){stringstr;//读取字符串intr,c,k,a[101][101],cnt=0;//数组a用来存储棋盘cin>>r>>c>>k;//r表示行,c表示列,k表示线段长度for(inti=1;i){cin>>str;//输入for(intj=1;j){if(str[j-1]=='.')//将棋盘字符转为数值表示是否可以放置a[i][j]=0;//0表示可以放置elsea[i][j]=1;//
