有关vector的存图用法

const int N=1e5+10;
vector<int> G[N];
void addedge(int u,int v){
	G[u].push_back(v);
	G[v].push_back(u);
}

const int N=1e5+10;
struct Edge{
	int v,w;
};
Edge make_Edge(int v,int w){
	Edge cur;cur.v=v;cur.w=w;return cur;
}
vector<Edge> G[N];
void addedge(int u,int v,int w){
	G[u].push_back(make_Edge(v,w));
	G[v].push_back(make_Edge(u,w));
}

Pair：
vector<pair<int,int> >G[N];
void addedge(int u,int v,int w){
	G[u].push_back(make_pair(v,w));
	G[v].push_back(make_pair(u,w));
}
