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…
Q3: Interplanetary Spaceflight Milan Tusk is the richest person in the universe. After devoting decades of his life to further our space exploration technologies, he’s finally ready to retire. Being a space enthusiast, the first thing he wants to do is visit n planets p1, p2, …, pn, in this order. He’s currently on planet p0. Milan knows that the distance between planets pi and pi + 1 (for 0 ≤ i < n) is d[i]light years. His spaceship uses 1 tonne of fossil fuels per light year. He starts with a full tank and can fill up his tank at any of the n planets (but he must not run out in between two planets). There’s a huge cost to set up the spaceship for refuelling. Due to financial constraints (he’s not THAT rich), he can fill up his tank at most ktimes. In order to save money and make his spaceship lighter, Milan is looking for the smallest possible fuel tank that enables him to complete his space travel and reach planet pn. What is the smallest tank capacity that enables him to do so?…
please code in python A mining company conducts a survey of an n-by-n square grid of land. Each row of land is numbered from 0 to n-1 where 0 is the top and n-1 is the bottom, and each column is also numbered from 0 to n-1 where 0 is the left and n-1 is the right. The company wishes to record which squares of this grid contain mineral deposits. The company decides to use a list of tuples to store the location of each deposit. The first item in each tuple is the row of the deposit. The second item is the column. The third item is a non-negative number representing the size of the deposit, in tons. For example, the following code defines a sample representation of a set of deposits in an 8-by-8 grid.deposits = [(0, 4, .3), (6, 2, 3), (3, 7, 2.2), (5, 5, .5), (3, 5, .8), (7, 7, .3)]Given a list of deposits like the one above, write a function to create a string representation for a rectangular sub-region of the land. Your function should take a list of deposits, then a set of parameters…
Computer Engineering HandsOn Lab: The Government of United States of America has decided to issue new currency notes with special protection features to so as to commemorate a great mathematician. They have decided to issue notes summing up to N and all the sums from 1 to N should only made by selecting some of the notes in only one unique way. With n = 5 the sets {1,1,1,1,1}, {1,2,2}, {1,1,3} are valid. Your task is to design a C++ code that output the solution in one line. Sample Input - 100 Sample Output - 3
C++ A robot is initially located at position (0; 0) in a grid [?5; 5] [?5; 5]. The robot can move randomly in any of the directions: up, down, left, right. The robot can only move one step at a time. For each move, print the direction of the move and the current position of the robot. If the robot makes a circle, which means it moves back to the original place, print "Back to the origin!" to the console and stop the program. If it reaches the boundary of the grid, print \Hit the boundary!" to the console and stop the program. A successful run of your code may look like:Down (0,-1)Down (0,-2)Up (0,-1)Left (-1,-1)Left (-2,-1)Up (-2,0)Left (-3,0)Left (-4,0)Left (-5,0)Hit the boundary! or Left (-1,0)Down (-1,-1)Right (0,-1)Up (0,0)Back to the origin! About: This program is to give you practice using the control ow, the random number generator, and output formatting. You may use <iomanip> to format your output. You may NOT use #include "stdafx.h".
Bus Loading Problem. You are in charge of filling busses with passengers at a bus terminal. Each bus has space for ten (10) passengers. Four (4) of those spaces can hold only wheelchair passengers, and the other six (6) can hold only non-wheelchair passengers. Busses and both types of passengers arrive at random. As busses arrive, you are to fill them up with passengers. Once a bus is full (containing 6 non-wheelchair, and 4 wheelchair passengers), it is allowed to leave the terminal, along with its passengers. You are responsible only for loading the passengers on the bus and having the bus depart. You do not need to worry about what happens to the busses or passengers after they leave. Each bus process has available to it the functions ArriveAtTerminal(), OpenDoors(), CloseDoors(), and DepartTerminal(). Each passenger process has available to it the functions ArriveAtTerminal() and GetOnBus(). Executing GetOnBus() loads the passenger on the bus, and the function returns when the…
Q1: Assignment Difficulty Dan has a list of problems suitable for Assignment 4. The difficulties of these problems are stored in a list of integers a. The i-th problem’s difficulty is represented by a[i] (the higher the integer, the more difficult the problem). Dan is too busy eating saltines to worry about Assignment 4 decisions, so he asks Michael the TA to select at least two problems from the list for the assignment. Since there are many possible subsets of the problems to consider and Michael has a life, he decides to consider only sublists (definition follows) of the list of problems. To make grading the assignment easier, Michael wants to pick problems that don’t vary too much in difficulty. What is the smallest difference between the difficulties of the most difficult selected problem and the least difficult selected problem he can achieve by selecting a sublist of length at least 2 of the original list of problems? Definition: A sublist of a list a is any list you can obtain…
Q3: Superheroes Supervillains are tired of Toronto condo rental prices, so they are leaving Toronto for Mississauga. Luckily, we have valiant superheroes that can deal with them. The superhero () has a name , an intelligence score , and a strength score .ni-th0 = gin[x] + s[x] Detective Zingaro has asked for your help. For each of the supervillains, tell him the name of the superhero that should deal with that supervillain. Note: A superhero can be assigned to multiple supervillains (or none at all). Note: whenever there are multiple superheroes that satisfy the given requirements for a supervillain, report the one whose name is lexicographically smallest (i.e. the one that’s the smallest according to Python’s ordering of strings). It’s guaranteed that superheroes have distinct names. Hint: Tuples of multiple elements may be helpful here. In python, you can compare two tuples and . If and are different, the result is the same as comparing and . If and are equal, the result is the same…
Knight's Tour: The Knight's Tour is a mathematical problem involving a knight on a chessboard. The knight is placed on the empty board and, moving according to the rules of chess, must visit each square exactly once. There are several billion solutions to the problem, of which about 122,000,000 have the knight finishing on the same square on which it begins. When this occurs the tour is said to be closed. Your assignment is to write a program that gives a solution to the Knight's Tour problem recursively. You must hand in a solution in C++ AND Java. The name of the C++ file should be "main.cc" and the name of the Java file should be "Main.java". Write C++ only with a file name of main.cc Please run in IDE and check to ensure that there are no errors occuring Output should look similar to: 1 34 3 18 49 32 13 16 4 19 56 33 14 17 50 31 57 2 35 48 55 52 15 12 20 5 60 53 36 47 30 51 41 58 37 46 61 54 11 26 6 21 42 59 38 27 64 29 43 40 23 8 45 62 25 10 22 7 44 39 24 9 28 63
1.In an ancient land, the beautiful princess Eve had many suitors. She decided on the following procedure to determine which suitor she would marry. First, all of the suitors would be lined up one after the other and assigned numbers. The first suitor would be number 1, the secondnumber 2, and so on up to the last suitor, number n. Starting at the first suitor she would then count three suitors down the line (because of the three letters in her name) and the third suitor would be eliminated from winning her hand and removed from the line. Eve would then continue, counting three more suitors, and eliminating every third suitor. When she reached the end of the line she would continue counting from the beginning. For example, if there were 6 suitors then the elimination process would proceed as follows:123456 initial list of suitors, start counting from 112456 suitor 3 eliminated, continue counting from 41245 suitor 6 eliminated, continue counting from 1125 suitor 4 eliminated, continue…
Use C language only. Create a program that will ask for Enter number of students: (for this example 2) Enter student 1's name: Enter student 1's age: Enter student 2's name: E nter student 2's age: At the end, the program shall display two class lists: one with arranged name (ascending order) and the other one arranged according to their age (ascending order). The two lists should contain the complete details of the students as follows: Sorted by name: 1. name, age 2. name, age Sorted by age: 1. name, age 2. name, age If the number of students is less than one, the program will display "no students to display." The letter case (uppercase or lowercase) shall have no bearing in the arrangement of names. Please use the "fgets()" in getting the name.
ISBNThis problem is slightly more difficult than the above problem. This one requires a data type that stores 10 digits. BackgroundPublishers and bookstores use a number system called the International Standard Book Number (ISBN) system to identify books. At the start of publication, each book is assigned a unique ISBN. An ISBN, once assigned, can never be re-used. Click here for detailed information on this numbering system.An ISBN consists of exactly 10 digits. The rightmost digit is the check digit. The check digit is validated modulo 11.• multiply each digit from the first to the ninth by a weight from 10 to 2 respectively (the first digit by 10, the second by 9,.., the ninth by 2).• the sum of the products plus the check digit should be divisible without remainder by 11.• if there is a remainder, the whole number is not a valid ISBN SpecificationsDesign a program that validates an ISBN. Your program keeps accepting a whole number and determining if that whole number is a valid…
