C++ lambda function error, while implementing dfs

Revision en5, by angry_pikachu, 2022-09-15 19:49:01

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);
