Hello Codeforcers!↵
↵
I'm encountering an issue with a recursive lambda DFS function in my code. Everything was working fine before, but now, after adding this function, I get an error. Can someone help me debug this and find out what's going wrong?↵
↵
Thanks!↵

Code :-↵
↵
~~~~~↵
int n; cin >> n;↵
vector<int> g[n];↵
for(int i=01; i<n; ++i) {↵
int u, v; cin >> u >> v;↵
u--; v--;↵
g[u].push_back(v);↵
g[v].push_back(u);↵
}↵
↵
string s; cin >> s;↵
↵
vector<int> leaf;↵
auto dfs = [&](auto &&self, int u, int par) {↵
for(auto &x : g[u]){↵
if(x==par) continue;↵
self(self, x, u);↵
}↵
if(g[u].size() == 1) leafs.push_back(u);↵
};↵
dfs(dfs,0,-1);↵
~~~~~↵
↵
Error :↵
