Solution: Find Nodes at k Distance from the Root
Explore how to use depth first search (DFS) to identify all nodes at a given distance k from a binary tree's root. Understand the recursive approach to traverse the tree, collect nodes, and analyze the solution's time and space complexity based on tree size and height.
