Leetcode 617. Merge Two Binary Trees
Given two binary trees, merge them into a new tree by traversing both from the roots and summing the values of overlapping nodes while using the non-null node when one side is missing. This is typically solved with a simultaneous DFS/BFS traversal (often recursive) that combines corresponding nodes.

Merge two n-ary trees. Given roots of 2 n-ary trees, write code to merge them following specific rules: 1) If nodes have the same name at the same level, combine their children and use the value from the second tree. 2) If a node has no corresponding match, add it directly. 3) Preserve the order of nodes based on their original position in both trees.
