//just push all the sources into the queue and perform simple bfs
vector<int> sources;
unordered_map<int,bool> vis;
unordered_map<int,int> dist;
queue<int> q;
for(int i = 0;i<sources.size();i++){
vis[sources[i]] = true;
dist[sources[i]] = 0;
q.push(sources[i]);
}
// then proceed as usual
while(!q.empty()){
int p = q.front();
q.pop();
for(int i = 0;i< g[p].size();i++){
if(!vis[g[p][i]]){
vis[g[p][i]] = true;
dist[g[p][i]] = dist[p] + 1;
q.push(g[p][i]);
}
}
