### Post-Order Traversal of a Binary TreeIn a post-order traversal of a binary tree, we visit the nodes in the following order: left subtree, right subtree, and then the root node. Let's use this approach to traverse the given binary tree and determine which nodes would be printed first and last.#### The Tree StructureThe tree is structured as follows:1. **Root Node (12)** - Left Subtree: - Node (6) - Left Subtree: - Node (2) - Left Subtree: - Node (1) - Right Subtree: - Node (4) - Right Subtree: - Node (8) - Right Subtree: - Node (18) - Left Subtree: - Node (13) - Right Subtree: - Node (23) - Left Subtree: - Node (19) - Right Subtree: - Node (29)#### Post-Order Traversal ExplanationTo perform a post-order traversal, we visit nodes in the following sequence:1. Traverse the left subtree of the root.2. Traverse the right subtree of the root.3. Visit the root node.Following this procedure for our tree:1. **Left Subtree of 12:** - **Left Subtree of 6:** - **Left Subtree of 2:** - Visit Node 1 (No children) - **Right Subtree of 2:** - Visit Node 4 (No children) - Visit Node 2 (after visiting children 1 and 4) - **Right Subtree of 6:** - Visit Node 8 (No children) - Visit Node 6 (after visiting children 2 and 8)2. **Right Subtree of 12:** - **Left Subtree of 18:** - Visit Node 13 (No children) - **Right Subtree of 18:** - **Left Subtree of 23:** - Visit Node 19 (No children) - **Right Subtree of 23:** - Visit Node 29 (No children) - Visit Node 23 (after visiting children 19 and 29) - Visit Node 18 (after visiting children 13 and 23) 3. Visit Root

In the post-order traverse, firstly we traverse the left subtree, then we move towards the right…

Refer to the tree on the picture and answer the following questions 1. Aside from its children, list 2 other descendants of node C. Your answer must be values that are adjacent when the nodes are arranged alphabetically in ascending order. For example, the descendant nodes are: ABX Y.

Given a binary tree, find the lowest common ancestor (LCA) of two given nodes in the tree. According to the definition of LCA on Wikipedia: "The lowest common ancestor is defined between two nodes v and w as the lowest node in T that has both v and w as descendants (where we allow a node to be a descendant of itself)." / 6 1 2 1 0 1 8 7 4 For example, the lowest common ancestor (LCA) of nodes 5 and 1 is 3. Another example is LCA of nodes 5 and 4 is 5, since a node can be a descendant of itself according to the LCA definition.
Correct answer will be upvoted else Multiple Downvoted. Computer science. You are given n chains of lengths l1,l2,… ,ln. You intend to fabricate a tree utilizing some of them. Every vertex of the tree is either white or dark. The tree at first just has a white root vertex. All chains at first comprise just of white vertices. You can take one of the chains and interface any of its vertices to any white vertex of the tree with an edge. The chain turns out to be important for the tree. The two endpoints of this edge become dark. Each chain can be utilized close to once. A few chains can be left unused. The distance between two vertices of the tree is the number of edges on the most brief way between them. Assuming there is essentially k white vertices in the subsequent tree, the worth of the tree is the distance between the root and the k-th nearest white vertex. What's the base worth of the tree you can get? In case it is absolutely impossible to construct…

A binomial tree, Bn is defined recursively as follows. B0 is the tree with a single vertex.Create Bn+1, where n is a nonnegative integer, by making two copies of Bn; the first copy becomes the root tree of Bn+1, and the second copy becomes the leftmost child of the root in the first copy.Here are examples for n = 0 to 3: A. Create a table that has the number of nodes in each depth, d, of B0 to B4, where d ≥ 1 (you should NOT have to draw B5!). B. What do you think the answers for problem d, above, for B5?
