#include<bits/stdc++.h>
#define int long long
using namespace std;
const int N=1e6+5;
inline int read(){
	int x=0,f=1;char ch=getchar();
	while(!isdigit(ch)){if(ch=='-')f=-1;ch=getchar();}
	while(isdigit(ch)){x=(x<<1)+(x<<3)+ch-48,ch=getchar();}
	return x*f;
}
int n,k,tot;
pair<int,int> ans[N];
map<pair<int,int>,bool> mp;
signed main(){
	n=read(),k=read();
	for(int i=1;i<=n;i++)
		ans[i*2-1]={i,i},mp[{i,i}]=1;
	for(int i=1;i<n;i++)
		ans[i*2]={i+1,i},mp[{i+1,i}]=1;
	ans[n*2]={1,n},mp[{1,n}]=1;
	tot=2*n;
	k-=2*n;
	for(int i=1;i<=n;i++){

	}
	return 0;
}

这程序好像有点Bug,我给组数据试试?
