Below are the top 3 levels of the game tree (tree of all continuations) of 2x2 go, with symmetry pruning. Each pass move is shown as an empty circle. Draw the next two levels of the game tree (you can prune for symmetry).
3.2.5 Assume we are given the option to insert the search keys in any order we like and that we are aware of how frequently a BST will need to access them.Should the keys be added to the tree in a different order, or in order of decreasing likelihood of access? Describe your response. 3.2.6 Add the tree's height-calculating method height() to BST. Create two implementations: a recursive method that adds a field to each node in the tree and takes linear space and constant time every query, and a method similar to size() that takes linear space and constant time per query. 3.2.5 Assume we are given the option to insert the search keys in any order we like and that we are aware of how frequently a BST will need to access them.Should the keys be added to the tree in a different order, or in order of decreasing likelihood of access?

You are implementing a binary search tree class from scratch, which, in additionto insert, find, and delete, has a method getRandomNode() which returns a random nodefrom the tree. All nodes should be equally likely to be chosen. Design and implement an algorithm for getRandomNode, and explain how you would implement the rest of the methods.

In class we drew the left part of the recursive call tree for the subset method when invoked on “ABC”. Draw the right part of the recursive subset tree when invoked on “ABC”. Use the same notation that we used in class.
You are creating from scratch a binary search tree class with the methods insert, find, and delete in addition to the method getRandomNode(), which retrieves a random node from the tree. There should be an equal chance of selecting each node. Create a getRandomNode algorithm, put it into practise, and describe how you'd develop the other functions.
a. For the graph below, give the order in which Dijkstra’s Algorithm would visit each vertex, starting from vertex A. 3 2 B F A G 4 ( E 4 D H 4 b. Change one of the weights in the graph so that the shortest paths tree returned by Dijkstra's is not correct. Hint: we showed in class that Dijkstra’s returns the correct SPT as long as all edges are non- negative. Set the weight of the edge connecting vertex . and vertex to c. Suppose we use the following heuristic: h(A) = 2 h(B) = 2 h(C) = 20 h(D) = 2 h(E) = 6 h(F) = 2 h(G) = 0 2 %3D h(H) %3D Recall that A* is just Dijkstra’s algorithm, except that vertices are given a priority equal to the sum of their Dijkstra priority (distance from the source) plus the heuristic distance, and also that we quit when the target is visited. Give the path (not order visited) that A* returns from A to G, you may not need all of the blanks: _A_ 2.

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…
