Drop some BFS problems..
By programmer5777, history, 4 hours ago, In English

Recently I learned BFS but, there aren't any BFS tag on CodeForces. as a new BFS learner I want to solve some BFS problems(so I can make BFS one of my strong topic) Please drop some problem which you think will help me to know the beauty of BFS more. consider the rating range between{1300-2000}.

      Unfortunately, not every bfs problem you solve will just be bfs. You might have to learn some new things along the way.

      I saw this bfs problem the other day: https://codeforces.net/problemset/problem/1775/D. I think that it is very educational.
