• Problem: https://judge.u-aizu.ac.jp/onlinejudge/description.jsp?id=GRL_5_C

Depends on

• ダブリング (library/dp/doubling.hpp)
• 辺 (library/graph/base/edge.hpp)
• グラフ (library/graph/base/graph.hpp)
• BFS (library/graph/shortest_path/bfs.hpp)
• LCA (library/graph/tree/lca.hpp)
• テンプレート (template/template.hpp)

Code
