Explanation of Solution
Representing vertices:
The vertices in a graph can be stored in an “array” or a “list”.
Example:
Consider the below graph:
The vertices from above graph has been stored in an array as follows:
String[] Ver={“A”, “B”, “C”, “”D”};
Representing edges using an “array”:
The edges in a graph can be stored in a “two-dimensional array”. This representation is called an “edge array”.
Example:
Consider the edges in an above graph can be stored using following two- dimensional array initialization:
int[][]={{0,1}, {0,2},{1,0},{1,2},{2,0},{2,1},{2,3},{1,3},{3,1},{3,2}};
Representing edges using an “edge object”:
Edges can also be stored as edge object by defining the edges as “objects” and store the edges in an “ArrayList”.
Example:
Consider the following “Edge” class object declaration:
Java,util.ArrayList<Edge>edges=new java.util.ArrayList<>();
Edges...

- Java please and thank you.arrow_forward: Imagine a histogram (bar graph). Design an algorithm to compute thevolume of water it could hold if someone poured water across the top. You can assume that eachhistogram bar has width 1.EXAMPLE (Black bars are the histogram. Gray is water.)lnput:{0, 0, 4, 0, 0, 6, 0, 0, 3, 0, 5, 0, 1, 0, 0, 0}arrow_forwardUsing the graph in the question: Write Java code to create an Adjacency Matrix M to represent the graph. Write Java code to create an Adjacency List L to represent the graph.arrow_forward
- Write a code that can be used to plot a 3D graph where x & y are between -5 to 5 and z is defined by the following equation. “z=4x4y - 3x3y2 + x”arrow_forwardSuppose you have a graph with N vertices. What is the largest number of edges it may have? log N What is the smallest number of edges it may have? N Suppose the graph is represented with an adjacency list. Call the number of edges M. What is the best description of the size of the graph (amount of memory required to store it)? O(N+M) + Suppose the graph is represented with an adjacency matrix. Call the number of edges M. What is the best description of the size of the graph (amount of memory required to store it)? O(N*M) + xarrow_forwardUsing Matplotlib (based on python), write a code that takes the input of two different functions. The first function should be displayed first on a graph. Program such that the graph gradually transforms into the second function.arrow_forward
- What is the maximum number of colors the edges of a planar graph can be colored with? Four?arrow_forwardGive a planar drawing of the graph with degree sequence (1, 1, 1, 2, 3, 3, 3, 3, 3, 3, 3, 3, 4, 4, 7). (Create the drawing in any drawing editor and include it as an image in your answer.)arrow_forwardWrite/modify MATLAB code and create a properly labeled graph.
