The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Note: Please Answer in java language only. Input 1 1 hasan jaddouh Output hasan

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 follow. The i-th one…

Computer Science Question Lab There is only one list of N ingredients in the menu. Every ingredient has its beauty value that does not depend on its taste, but on the way it looks, which is expressed as a positive integer. To order a dish, the customer asks Ramsay to use all the ingredients from L to R (L is strictly less than R). Ramsay knows that the dish will be tasty and not only beautiful if the sum of its ingredients' beauty values is divisible by K. Ramsay does not want to use all the ingredients, so he always excludes one of them. Which one? - The least beautiful one! (in other words - which has the minimal beauty value). Now he wonders - how many segments (L,R) are there such that the sum of their beauty values will be divisible by K after excluding the least beautiful ingredient. Your assignment is to develop a python code that prints the answer for the problem. Sample test case are given below:Input:3 51 2 3Output:1
Williams and Tuner have invented a new game called Strip-Pennies. The game is played with their coins and a strip of paper divided into cells. The cells are numbered from the left, starting from 1. Williams and Tuner put some coins at some random cells on the strip, each coin in a cell. They alternatively take their turn to play the game. At each step, a player must take a coin and move it to a cell to the left of it. There is at most one coin in a cell at any time of the game. Of course, a coin cannot jump over another coin. Whoever cannot move loses the game. Tuner takes her turn first. Develop a python code to find out who wins the game, if Tuner could win the game, show her a winning move. If there are several winning moves, show her the winning move that uses the leftmost possible coin. If there are still several moves, show her the move that moves the coin as far as possible to the left. Sample Input: 1 3 135 Sample Output: Tuner wins Move 5 to 4
Step 3: Complete the public boolean checkWin(int[][] board) method. In order to check if a puzzle is solved or not, we need to check if the current puzzle satisfy the row rule, column rule, and grid rule. So that is to check if every row of the puzzle contains the number 1 to 9 exactly once, every column contains the number 1 to 9 exactly once, and every 3X3 subgrid contains the number 1 to 9 exactly once. The nested loops for checking rows are given to you for your reference. Read the comments to understand it. Then complete the code to check the columns and the subgrids This is step three. On this practice problem we were given an incomplete java file that is being used to solve a suduko board. Ill try to copy and paste the code I have so far down below but I dont know how well that will work. import java.util.Arrays;import java.util.Random; public class Sudoku { public static final int[][] BOARD = {{4, 3, 5, 8, 7, 6, 1, 2, 9},{8, 7, 6, 2, 1, 9, 3, 4, 5},{2, 1, 9, 4, 3, 5, 7, 8,…

In the Dice Roll game, the player begins with a score of 1000. The player is prompted for the numberof points to risk and a second prompt asks the player to choose either high or low. The player rollstwo dice and the outcome is compared to the player’s choice of high or low. If the dice total is between2 and 6 inclusive, then it is considered “low”. A total between 8 and 12 inclusive is “high”. A total of7 is neither high nor low, and the player loses the points at risk. If the player had called correctly, thepoints at risk are doubled and added to the total points. For a wrong call, the player loses the points atrisk. Create a DiceRollGame application that uses a DRPlayer object based on this specification. TheDRPlayer object should have two Die member variables that represent the dice. The Die class shoulduse a random number generator to determine the outcome in a roll() method. Application outputshould look similar to:

Task An ATM only has 100, 50 and 20 dollar bills (USD) available to be dispensed. Given an amount between 40 and 10000 dollars (inclusive) and assuming that the ATM wants to use as few bills as possible, determinate the minimal number of 100, 50 and 20 dollar bills the ATM needs to dispense (in that order). Here is the specification for the withdraw method you'll complete: withdraw(amount) Parameters amount: Integer - Amount of money to withdraw. Assume that the amount is always divisible into 100, 50 and 20 bills. Return Value Array (of Integers) - An array of 3 integers representing the number of 100, 50 and 20 dollar bills needed to complete the withdraw (in that order). Constraints 40 ≤ amount ≤ 1000 Can you please help me I will rate! Code is in Python 3.7
Jessie has a lot of cooking with her (N). He often remembered the first few letters of the recipe and forgot the others. Like all great chefs, Jessie re-calculated the recipes according to the priority. So, looking at the list of recipes and priorities answers Jessie's questions. Response from Jessie: Giving the first few letters of the recipe; you have to print the perfect recipe in the most important way. Note: Every recipe has a unique value. Please answer this in C++ Only Input 1 flour-with-eggs 100 1 G Output 0
The International Standard Book Number (ISBN) is a number that uniquely identifies a book. Publishers can buy or receive ISBNs from the International ISBN Agency. There are two types of ISBNs: ISBN-13 and ISBN-10, which are 10- and 13-digits long, respectively.ISBN-10 has a pattern, where the last digit can be found using the first 9. Additionally, ISBN-10 can also be used to calculate its ISBN-13 equivalent (and vice versa). Write two functions in ISBN.java. The main method is implemented for you so you can test your functions. Instructions on how to run this file to make use of the test.txt file are detailed below. calculateISBN10(int[] isbn) computes the last digit of the ISBN-10 number. The first 9 of the 10 digits of the ISBN will be passed to the function as the parameter isbn integer array of size 10. The last integer in the array will be -1. Your job is to calculate the last digit (called the check digit), and update the last index of the isbn array with the computed…
