Dive into the LeetCode problem "Maximize the Number of Target Nodes After Connecting Trees I"! This video breaks down how to approach this tree-based challenge. We explore the core strategy: for each node in the first tree, we count its local targets (within k hops) and then add the maximum possible targets from the second tree. The key insight involves realizing that connecting the two trees uses one edge, leaving a k-1 hop budget for exploring the second tree. We'll walk through precomputing the optimal contribution from Tree2 and then applying it, using Depth-First Search (DFS) to count reachable nodes. Full Python code explanation and time/space complexity analysis included!

Perfect for coding interview preparation and improving problem-solving skills.
