Binary lifting questions
WebApr 29, 2024 · The idea behind binary lifting is that when we climb the tree from a vertex, instead of moving one vertex at a time, we move in powers of 2. For example, if we want to climb up 19 vertices, we first climb 16 vertices, then 2 vertices, and then 1. This will make the query to return in O(logn).
