Chapter 29, Problem 29.9PE

(Find a minimum spanning tree) Write a program that reads a connected graph from a file and displays its minimum spanning tree. The first line in the file contains a number that indicates the number of vertices (n). The vertices are labeled as 0,1,..., n-1. Each subsequent line describes the edges in the form of u1, v1  w1 | u2, v2, w2 |…. Each triplet in this form describes an edge and its weight. Figure 29.23 shows an example of the file for the corresponding graph. Note we assume the graph is undirected. If the graph has an edge (u, v), it also has an edge (v, u). Only one edge is represented in the file. When you construct a graph, both edges need to be added.

FIGURE 29.23 The vertices and edges of a weighted graph can be stored in a file.

Your program should prompt the user to enter a URL for the file, read data from the file, create an instance g of WeightedGraph, invoke g.printWeightedEdges() to display all edges, invoke getMinimumSpanningTree() to obtain an instance tree of WeightedGraph.MST, invoke tree.getTotalWeight() to display the weight of the minimum spanning tree, and invoke tree.printTree() to display the tree. Here is a sample run of the program:

The number of vertices is 6

Vertex 0: (0, 2, 3) (0, 1, 100)

Vertex 1: (1, 3, 20) (1, 0, 100)

Vertex 2: (2, 4, 2) (2, 3, 40) (2, 0, 3)

Vertex 3: (3, 4, 5) (3, 5, 5) (3, 1, 20) (3, 2, 40)

Vertex 4: (4, 2, 2) (4, 3, 5) (4, 5, 9)

Vertex 5: (5, 3, 5) (5, 4, 9)

Total weight in MST is 35

Root is: 0

Edges: (3, 1) (0, 2) (4, 3) (2, 4) (3, 5)

C++ Coding: Arrays Implement a 4x4 two-dimensional array of integers. Use a nested loop to populate the array with random values 0 to 100 inclusive. Use a nested loop to output the array as a grid. Use a single loop to output all elements in the third row. Use a single loop to output all elements in the first column. Use a single loop to output all elements in the first diagonal (r==c). Use a single loop to output all elements in the opposing diagonal. Example Output: 10 75 67 8820 66 55 4831 57 93 3943 76 81 71Row 3: 31 57 93 39Col 1: 10 20 31 43Diagonal 1: 10 66 93 71Diagonal 2: 88 55 57 43
please code in python Forbidden concepts: arrays/lists (data structures), recursion, custom classes You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen.The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: (refer image1 ) Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k X k grid consisting only of that character. Input Specification:The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. [refer image2]
[Python Language] Using loops of any kind, lists, or is not allowed. Angela loves reading books. She recently started reading an AI generated series called “Harry Trotter”. Angela is collecting books from the series at her nearest bookstore. Since the series is AI generated, the publishers have produced an infinite collection of the books where each book is identified by a unique integer. The bookstore has exactly one copy of each book. Angela wants to buy the books in the range [l,r], where l ≤ r. As an example, the range [−3,3] means that Angela wants to buy the books  − 3,  − 2,  − 1, 0, 1, 2, and 3. Dan also loves the series (or maybe annoying Angela – who knows, really), and he manages to sneak into the bookstore very early to buy all of the books in the range [d,u], where d ≤ u. When Angela later visits, sadly she will not find those books there anymore. For example, if Angela tries to buy books [−2,3] and Dan has bought books [0,2], Angela would only receive books  − 2,  − 1,…
