code complete application that includes all the code for computing the shortest paths using Dijkstra’s algorithm, along with a program to test the implementation:
Background: When searching for an item in a list, each item that we examine (compare) is considered to be interrogated. If we search for John, the following names are interrogated: Harry, Larry, John (in that order). If two names tie for the middle position, choose the first of the two names for the middle.If we search this same list for John using the Sequential search we would interrogate all the names from Alice through John. We would start with Alice, move to Bob, move to Carol and so forth until we reached John. Directions: Use the original list of names (Alice - Oliver) to answers questions 1-8. Using a sequential search, what names are interrogated to find Carol? Using a sequential search, what names are interrogated to determine that Sam is not in the list? Using a binary search, what names are interrogated to find Carol? Using a binary search, what names are interrogated to determine that Sam is not in the list? Will a binary search or sequential search find Alice…
a) Write a program that asks user to enter number of vertices in a directed graph and thenthe adjacency matrix representing the directed graph. The program, then, must display thenode with the highest outdegree. Assume that nodes are named as 0, 1, 2 and so on.
Write a program that animates the linear search algorithm. Create a list that consists of 20 distinct numbers from 1 to 20 in a random order. The elements are displayed in a histogram, as shown in Figure 10.17. You need to enter a search key in the text field. Clicking the Step button causes the program to perform one comparison in the algorithm and repaints the histogram with a bar indicating the search position. When the algorithm is finished, display a dialog box to inform the user. Clicking the Reset button creates a new random list for a new start.

Q1: Draw a map of the process of reading the grades of 100 students in mathematics and determine whether the student benefits from the decision score prints the word Pass and not prints Fail.
3.)Declare variables a. The images variable containing an HTML collection of all elements with the tag name "img". b. The photoBucket variable referencing the element with the id "photo_bucket". c. The photoList variable referencing the element with the id "photo_list". 4.) Create a for loop that iterates through all of the items in the images collection. 5.) Within the for loop insert an onclick event handler that runs an anonymous function when an image is clicked. 6.) When an image is clicked it is either moved from the photo bucket to the photo list or from the photo list back to the photo bucket. To determine which action to perform, add the following if else statement to the anonymous function: a. If the parent element of the clicked image has an id equal to "photo_bucket" then do the following: (i) Create an element node named newltem for the li element, (ii) append newltem to the photoList object, and (i) append the image to the newltem object using the appendChild() method.…
Q1: Research Groups In response to popular demand, Dan’s established two research groups A and B composed of his n graduate students. Each of these students is a member of exactly one of the two groups at any given time. The students are numbered from 1 to n in some arbitrary order. To measure the success of his research groups, Dan assigns a citation score to each of them. Initially, both groups have citation score 0. Throughout the semester, events of the following two types happen: Student x publishes a paper in which they cite student y’s work (youcan assume all of the students have been around long enough to have prior research that can be cited). As a result, If x and y are in the same group, their group’s citation score increases by 1. If x and y are in different groups, y’s group’s citation score increases by 5. Dan changes student x’s group (from A to B or from B to A) to have them work on different projects. To assess the overall success of the research groups, Dan…
