- Code in Java only In a rooted tree, the lowest common ancestor (or LCA for short) of two vertices u and v is defined as the lowest vertex that is ancestor of both that two vertices. Given a tree of N vertices, you need to answer the question of the form "r u v" which means if the root of the tree is at r then what is LCA of u and v. Input: 4 12 23 14 2 142 242 Output: 1 2In Python the only import that may be used is Numpy Implement a function called page_rank which will take as input a numpy array M, which will represent the transition matrix of a directed graph, and a positive integer n. The output will be a numpy array which gives the page ranks of each vertex in the graph represented by M. You will iterate the update process n times.Given below is the implementation of the bellman ford and dijkstras algorithm.

- Using the C Programming language, write a program that sums an array of 50 elements. Next,optimize the code using loop unrolling. Loop unrolling is a program transformation that reduces thenumber of iterations for a loop by increasing the number of elements computed on each iteration.Generate a graph of performance improvement."Dijkstra's single-source shortest path algorithm returns a results grid that contains the lengths of the shortest paths from a given vertex [the source vertex] to the other vertices reachable from it. Develop a pseudocode algorithm that uses the results grid to build and return the actual [shortest] path, as a list of vertices, from the source vertex to a given [target] vertex. (Hint: This algorithm starts with a given vertex [the target vertex] in the grid's first column and gathers ancestor [parent] vertices, until the source vertex is reached.)" *For your algorithm, assume that grid is the name of the results grid produced by Dijkstra's single-source shortest path algorithm. *Each vertex is identified by its label/name, which is in column 1 of grid. *As the first step of your algorithm, find the name of the source vertex. *Next, get the name of the target vertex from the user. Pseudocode should avoid details through broad-stroke statements. However, it must give enough information…In Python the only import that may be used is Numpy A function called ttransition_matrix, which will take as input a directed graph object G. The function will return a numpy array which represents the transition matrix of the graph. You may assume that the vertices of G have labels from 0 to |V | − 1 where |V | is the number of vertices in the graph
- Recursive filtering techniques are often used to reduce the computational complexity of a repeated operation such as filtering. If an image filter is applied to each location in an image, a (horizontally) recursive formulation of the filtering operation expresses the result at location (x +1, y) in terms of the previously computed result at location (x, y). A box convolution filter, B, which has coefficients equal to one inside a rectangular win- dow, and zero elsewhere is given by: w-1h-1 B(r, y,w, h) = ΣΣΤ+ i,y + ) i=0 j=0 where I(r, y) is the pixel intensity of image I at (x, y). We can speed up the computation of arbitrary sized box filters using recursion as described above. In this problem, you will derive the procedure to do this. (a) The function J at location (x,y) is defined to be the sum of the pixel values above and to the left of (x,y), inclusive: J(r, y) = - ΣΣ14.0 i=0 j=0 Formulate a recursion to compute J(r, y). Assume that I(r, y) = 0 if r <0 or y < 0. Hint: It may be…java code will need to return the traversal of the nodes in DFS order, wherethe traversal starts from Node/Vertex 0.When you follow the traversal process as specified - the complexity of the solution will be linear as shown below.Time Complexity: O(V + E), where V is the number of Vertices andE is the number of Edges respectively.Space Complexity: O(V )The linear space complexity would come from the recursion (AKA ”recursionstack”) you employ to traverse the Graph.Write a complete C++ program that implements the Breadth First Search (BFS) Algorithm (Chapter 22).
