I am getting error

prog.cpp: In lambda function:

prog.cpp:118:28: error: use of ‘dfs’ before deduction of ‘auto’

118 | for(ll it: nde[i]) dfs(it,fren[i]);

In this code , ll means long long, nde[i] is a vector of int

auto dfs = [&](int i,int x)->void{
        fren[i]+=x;
        for(ll it: nde[i]) dfs(it,fren[i]);
    };
dfs(0,0);
