实际上,这就是DFS的框架。根据框架写出对应的程序,即为本题目的解。 AC Code #include <bits/stdc++.h> usingnamespacestd; constintN=1e6+10; boolflag=0; charg[2][2*N]; intn=0; //!dfs方向:tar = l向左,r向右,u向上,d向下 voiddfs(intx,inty,chartar){ if(y>=n)return; if(x==1&&...

如果结点数是奇数,则不满足题意,输出-1.否则就dfs寻找所有结点的子结点数,如果子结点数量为偶数,则说明可以删除一条边。 AC代码 代码语言:javascript 复制 #include<bits/stdc++.h> #define x first #define y second #define PB push_back #define mst(x,a) memset(x,a,sizeof(x)) #define all(a) ...
