rt，代码如下

#include<bits/stdc++.h>
using namespace std;
int n,m,g[100010][100010];
int main(){
    memset(g,100000,sizeof(g));
    cin>>n>>m;
    for(int i=1;i<=m;i++){
        int u,v,w;
        cin>>u>>v>>w;
        g[u][v]=min(g[u][v],w);
        g[v][u]=min(g[v][u],w);
    }
    for(int k=1;k<=n;k++){
        for(int i=1;i<=n;i++){
            if(i!=k){
                for(int j=1;j<=n;j++){
                    if(j!=i&&j!=k&&g[i][k]+g[k][j]<g[i][j])
                        g[i][j]=g[i][k]+g[k][j];
                }
            }
        }
    }
    for(int i=1;i<=n;i++){
        for(int j=1;j<=n;j++){
            if(g[i][j]==100000) cout<<0<<" ";
            else cout<<g[i][j]<<" ";
        }
        cout<<endl;
    }
    return 0;
}
