Can you solve this real interview question? Linked List in Binary Tree - Given a binary tree root and a linked list with head as the first node. Return True if all the elements in the linked list starting from the head correspond to some downward path
Given a binary tree, flatten it to a linked list in-place. For example, given the following tree: 1 / \ 2 5 / \ \ 3 4 6 The flattened tree should look like: 1 \ 2 \ 3 \ 4 \ 5 \ 6 1. 2. 3. 4. 5. 6. 7.
Given a binary tree, flatten it to a linked list in-place. For example, Given 代码语言:javascript 代码运行次数:0 运行 AI代码解释 1/\25/\ \346 The flattened tree should look like: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 ...
A binary heap is a tree created using a binary tree. It can be seen as a binary tree with two additional constraints: Shape property: A binary heap is a complete binary tree; that is, all levels of the tree, except possibly the last one (deepest) are fully filled, and, if the last...
Breadth-first traverse iterative traverse of tree.This is an old one: instead of using a stack (implicit function call stack, or an explicit data structure), the algorithm uses a FIFO queue to keep track of its place in the traverse of the tree....
To compute the height of a tree, start at its leaf nodes and assign them a height of 0. Then move up the tree using the three rules outlined to compute the height of each leaf nodes' parent. Continue in this manner until every node of the tree has been labeled. The height of the ...
