Given an n-ary tree, return the level order traversal of its nodes' values. (ie, from left to right, level by level). For example, given a 3-ary ...
Design an algorithm to encode an N-ary tree into a binary tree and decode the binary tree to get the original N-ary tree. An N-ary tree ...
Given a n-ary tree, find its maximum depth. The maximum depth is the number of nodes along the longest path from the root node down ...
Serialization is the process of converting a data structure or object into a sequence of bits ...
We run a preorder depth first search on the `root`of a binary tree. At each node in this traversal, we output D dashes (where D is the depth ...
Given a binary tree, return the preorder traversal of its nodes' values. Example: Follow up: Recursive solution is trivial, could you do ...
Given a binary tree with N nodes, each node has a different value from {1, ..., N}. A node in this binary tree can be flipped by swapping the left ...
