In a bank, customers wait in a queue (q0) for their turn to complete a transaction. Customers who come first are served first. At a certain point when there are lots of customers waiting, a decision is taken to split the queue elements into two empty queues q1 and q2. The customers are split based on the alphabetical order of their first names. Customers with first name starting A-H are added to q1 while the others (first name starting I-Z) are added to q2. In an application, write a method named splitQueue (in an application) that accepts as parameters 3 queues, the original queue (q0) and two empty queues (q1 and q2) to be filled as described above. Write also a main method in which you read the first names of customers from the user, fill them into q0 and call the method splitQueue to split q0 elements into q1 and q2. After the split display the elements of q1 first then those of q2. The header of the method is: public static void splitQueue ( Queue q0, Queue q1, Queue q2) Note:…
Suppose there are two singly linked lists both of which intersect at some point and become a single linked list. The head or start pointers of both the lists are known, but the intersecting node is unknown. Also, the number of nodes in each of the list before they intersect are unknown and both the list may have it different. List1 may have n nodes before it reaches intersection point and List2 might have m nodes before it reaches intersection point where m and n may be m = n, m > n or m < n. Give an algorithm for finding the merging point. Hints: A brute force approach would be to compare every pointer in one list with every pointer in another list. But in this case the complexity would be O(mn)
Tour.java Create a Tour data type that represents the sequence of points visited in a TSP tour. Represent the tour as a circular linked list of nodes, one for each point in the tour. Each Node contains two references: one to the associated Point and the other to the next Node in the tour. Each constructor must take constant time. All instance methods must take time linear (or better) in the number of points currently in the tour. To represent a node, within Tour.java, define a nested class Node: private class Node { private Point p; private Node next; } Your Tour data type must implement the following API. You must not add public methods to the API; however, you may add private instance variables or methods (which are only accessible in the class in which they are declared). public class Tour // Creates an empty tour. public Tour() // Creates the 4-point tour a→b→c→d→a (for debugging). public Tour(Point a, Point b, Point c, Point d) // Returns the number of points in this tour. public…
You want to buy a ticket for a well-known concert which is happening in your city. But the number of tickets available is limited. Hence the sponsors of the concert decided to sell tickets to customers based on some priority. A queue is maintained for buying the tickets and every person is attached with a priority (an integer, 1 being the lowest priority). The tickets are sold in the following manner - 1. The first person (pi) in the queue requests for the ticket. 2. If there is another person present in the queue who has higher priority than pi, then ask pi to move at end of the queue without giving him the ticket. 3. Otherwise, give him the ticket (and don't make him stand in queue again). Giving a ticket to a person takes exactly 1 minute and it takes no time for removing and adding a person to the queue. And you can assume that no new person joins the queue. Given a list of priorities of N persons standing in the queue and the index of your priority (indexing starts from 0). Find…
A Queue is a special array where the insertion and deletion will be via a specific index called "head". A Queue is characterized by 3 attributes: a. capacity (int): the maximum number element Member that can be contained into the Queue; b. head: presents the index where we can add/remove element to the Queue. The head value presents also the current number of elements into the Queue. When a Queue is created the initial value of head is 0; c. Member content[]: an array of elements of type Member; Creates the class Queue with the following methods: a. a Constructor able to create a Queue with maximum 10 Members; b. bool empty (): this method returns true if no element exists in the Queue c. bool full(): this method returns true if there are no place to add a new element to the Queue; d. overload the operator += (Member): able to add an element to the Queue. You need to be sure that there is an available space in the Queue (use the assert function). e. delete(): able to delete an element…
1. Using the above class map, write function void map::mapToGraph(graph &g){...} to create a graph g that represents the legal moves in the map m. Each vertex should represent a cell, and each edge should represent a legal move between adjacent cells. 2. Write a recursive function findPathRecursive(graph &g, stack &moves) that looks for a path from the start island to the destination island. If a path from the start to the destination exists, your function should call the map::printPath() function that should print a sequence of correct moves (Go left, Go right, Go down, Go up, etc.). If no path from the start to the destination exists, the program should print, "No path exists". If a solution exists the solver should also simulate the solution to each map by calling the map::print() function. The map::print() function prints out a map visualization, with the goal and current position of the car in the map at each move, marked to show the progress. Hint: consider recursive-DFS. 3.…
In this project, you will develop algorithms that find road routes through the bridges to travel between islands. The input is a text file containing data about the given map. Each file begins with the number of rows and columns in the map considered as maximum latitudes and maximum longitudes respectively on the map. The character "X" in the file represents the water that means if a cell contains "X" then the traveler is not allowed to occupy that cell as this car is not drivable on water. The character "0" in the file represents the road connected island. That means if a cell contains "0" then the traveler is allowed to occupy that cell as this car can drive on roads. The traveler starts at the island located at latitude = 0 and longitude = 0 (i.e., (0,0)) in the upper left comer, and the goal is to drive to the island located at (MaxLattitude-1, MaxLongitudes-1) in the lower right corner. A legal move from an island is to move left, right, up, or down to an immediately adjacent cell…
Python Language Q2: Ginormous Campus The campus is pretty big. There are n buildings scattered around it, numbered from 0 to n-1. These buildings are so far away from each other that the only way to get from one to another is to take a campus bus. There are m campus bus routes. The i-th one (0 <= i < m) takes you from building u_i to building v_i (but not the other way around). These buses run very frequently. Professor Zingaro is deciding where to hold his CS lectures. He believes a building x is accessible from a building y if you can get from y to x taking at most two buses. For his students’ convenience, he wants to hold his lectures in the most accessible building. Help him out by telling him how many buildings the most accessible building is accessible from. In addition, list all buildings that are the most accessible. Input The first line of the input contains two space-separated integers n and m, denoting the number of buildings and bus routes, respectively. m lines…
A transaction database is a set of transactions completed in a supermarket database. Each transaction is a set of items. For example, consider the following transaction database. It contains 5 transactions (t1, t2, ..., t5) and 5 items (1,2, 3, 4, 5). For example, the first transaction represents the set of items 1, 3 and 4. It is important to note that an item is not allowed to appear twice in the same transaction and that items are assumed to be sorted by lexicographical order in a transaction. Transaction id Items t1 {1, 3, 4} t2 {2, 3, 5} t3 {1, 2, 3, 5} t4 {2, 5} t5 {1, 2, 3, 5} What is the output of the Apriori algorithm run on the previous transaction database with a minimum support of 40 % (2 out of 5 transactions)?
A group of researchers hired you to develop a system to manage the execution of their computing jobs (tasks) in a piece of equipment. This cquipment can only execute one job at a time. Thus, you need to create a Queue class to queue jobs. The queue can be associated with one of the following strategies for selecting jobs: First In First Out (FIFO). Lowest First (LF), and Last In First Out (LIFO). Use the Strategy design pattern for representing these strategies and their association to Queue. Draw a UML diagram
In Python Programming language USING AVL TREE Building an automatic appointment reservation system for a very busy heart surgeon in the city. The system is going to work as follows: The patient requests for an appointment time. The system looks through the list of appointments and if there are no appointments scheduled within 10 minutes either way of the requested time, then that appointment is added to the list of appointments along with the patient ID. Otherwise, the patient is given the next available time automatically that is not within 10 minutes of any other scheduled appointment. At the appointed time, the appointment is marked as serviced and deleted from the list of appointments. You must use an AVL Tree to implement this appointment system. The reservation system should run as follows: It should run for a total of 12*25*60 minutes. At each time instant, there is a 10% probability that a new request comes in. If a new request comes in, generate a random number between the…
Monitors: Select all of the following statements that are true. A process enters a monitor by calling one of its procedures. Only one process may be active in a monitor at any given time. When the "Signal and Continue" approach (Mesa semantics) is applied, the signaling process P is placed on the Urgent Queue. F2 Monitors can be implemented using semaphores. The Mesa semantics lends to an efficient implementation of a monitor and reduces the number of context switches. 3 F3 # F4 $ 4 F5 % 5 F6 A 6 F7 8 & 7 F8 8 F9 prt sc F10 9 home F11 end F12 insert 7:15 Pa 10/17/202 delete
