Solution: Frog Position After T Seconds

Explore how to determine the probability that a frog, starting at vertex one, reaches a target vertex after t seconds in an undirected tree. Learn to simulate frog movements with breadth-first search, applying concepts like equal probability jumps, unvisited neighbors, and handling cases when the frog is stuck. This lesson provides a clear approach to solve the problem efficiently and understand the time and space complexities involved.
