I've written the solution for 543 B,I think it works fine but gets time limit on test 8.I ckecked and it doesn't pass inputing phase.How can it happen with 3000 numbers?

Use faster I/O. You can either use
ios_base::sync_with_stdio(0);cin.tie(0);
at the beginning of your program and continue using cin/cout or use scanf/printf.will it help on 3000 numbers?
If the problem with your code is not the algorithm, it should make a significant difference. Input with these techniques can be more than 5 times faster.
special for you fixed code .
research BFS implementation. for example
thanks very much,so was the problem in implementation of bfs?when i checked it failed during imputing and didn't even reach bfs part
i didn't consider map is logN just changing to unordered_map fixed it.
Your code awesome beautiful!!! Are you understand why std::map — TLE, std::unordered_set — AC ??
I used map instead of array because it can be cleared more easily, didn't think of it being too slow.
