Looking at question,Its dijstra implementation
using namespace std;
vector adj[200005]; ll mod=1e9+7; ar<ll,5> d[200005]; ll vis[200005]; int main(){
ll n,m; cin>>n>>m; while(m--){ ll x,y,w; cin>>x>>y>>w; adj[x].pb(mpa(y,w)); } for(ll i=1;i<=n;i++){ d[i][0]=i;//dest d[i][1]=(i==1?0:1e18);//distance d[i][2]=(i==1?1:0);//no of routes d[i][3]=(i==1?1:1e18);//min_nodes d[i][4]=(i==1?1:0);//max_nodes } set< ar<ll,5> > q; q.insert(d[1]); while(q.size()){ ar<ll,5> h=*q.begin(); q.erase(q.begin()); ll v=h[0]; vis[v]=1; for(const auto &u:adj[v]){ ll prop=d[v][1]+u.ss; ll to=u.ff; if(d[to][1] > prop){ if(q.find(d[to])!=q.end())q.erase(q.find(d[to])); d[to][1]=prop; d[to][2]=d[v][2]; d[to][3]=d[v][3]+1; d[to][4]=d[v][4]+1; q.insert(d[to]); }else if(d[to][1]==prop){ q.erase(q.find(d[to])); d[to][2]=(d[to][2]+d[v][2])%mod; d[to][3]=max(d[to][3],d[v][3]+1); d[to][4]=min(d[to][4],d[v][4]+1); q.insert(d[to]); } } } cout<<d[n][1]<<" "<<d[n][2]%mod<<" "<<d[n][4]-1<<" "<<d[n][3]-1;
}
Above is giving Wrong answer for 2 cases can anyone help me to find whats wrong in this
