Question: Solve this using C++ Candidate Boris is going to have a small walk. Bytetown can be represented as N- dimensional cube with edge size D. Initially Boris stands in cell with coordinates (0, 0, ... 0) and his destination is cell (D-1, D-1,... D-1). His route consists of chain of the cells, where each pair of consecutive cells differs in exactly one coordinate by 1 and sum of coordinates strictly increases during his walk. Note that Boris walks through the cells not points. But not all the people in Bytetown are going to vote for Boris. Some of them are sure that Boris is a liar and bribetaker and they will tell it to Boris if they meet him. Boris doesn't like such people and avoids them. He knows that at cell with coordinares (io, İ4,.., İN-1) he will meet (io^ i,^...^İN-1)×(io+ iq+...+ İN-1) such people (in other words XOR-sum of coordinates times arithmetic sum of coordinates). Try to help him to find minimal number of unfriendly people he will have to meet. Sample Input: 23…
All businesses want to keep their customers happy. To do that, many companies assign a certain amount of time to each customer to optimize the business. The alternative would be to hire more employees, which would lead to higher costs. This problem requires you to simulate how authorities optimize the number of cashiers at the entrance of a toll bridge to make sure drivers are satisfied. Make the following assumptions: There is one cashier per line. The line works as a queue with no cars cutting the line or leaving it. One car arrives at the entrance every 10 seconds. It takes 90 seconds (1.5 minutes) to process the payment, starting from the moment a cashier is available. Assume there is no pause between cars. Written in java, Your Tasks: Design class CarInLine, with the following specifications: The class has two instance variables: arrivalTime and DepartureTime, stored as integers. Define a constructor that accepts an integer as an argument representing the arrival time, in…

Instead, the application uses an algorithm that considers only the most important factors such as total distance and traffic congestion along popular routes.

A group of m people is considering sharing the cost of buying some items for their summer camp. There are a total of n possible items to purchase. Each person writes a list of the items they are interested in purchasing on a paper. For example, person one may write “boat, trampoline, hot tub,” whereas person two may write “ hot tub, kayak, paddleboard”. There is no limit to how many items a person registers on their sheet. The goal is to determine if at least k items can be purchased. The following rules apply 1. The cost of any purchased item must be split equally among all those who listed that item on their sheet. No person can refuse to contribute to an item chosen for purchase, which is listed on their sheet. 2. Since each person has a limited budget, they may only contribute to at most one item on their list. The problem of determining if at least k items can be purchased is called SummerCamp. Show that this problem is NP-complete.
A graph G with vertices labelled 0 to 9 is shown below. 8 17 3 Tick all the statements that are correct about the graph. You may need to compare the above graph to the Peterson graph, which is provided as follows: O Gis a Hamiltonian graph O G contains more than five spanning trees O Gis an Eulerian graph O G is a simple graph O Gis bipartite O The complement of G is connected There are two distinct vertices in G that are joined by an Eulerian trail O The diameter of G is 2 O There are two distinct vertices in G that are joined by a Hamiltonian path O Gis isomorphic to the Peterson graph G is a regular graph 6,
using Python programming language. The Towers of Hanoi is a classic puzzle that consists of 3 towers, and n disks of different sizes that can slide onto any tower. The puzzle starts with the disks sorted in ascending order of size from top to bottom. It has the following constraints:a. Only one disk can be moved at a time.b. A disk can only be moved from the top of one tower to another tower.c. A disk can only be placed on top of a larger disk. Write a pseudo-code.
