Which of the following is not true of a loop invariant? O If it is True just before entering the loop, it must also be True right after executing the last line of the loop, even if it temporarily stops being True somewhere within the body of the loop. O It is a proposition, and therefore evaluates to a True or False value. It must be a tautology. If the loop invariant is True before entering a loop, the loop entry condition may still be False, meaning that the loop would not be executed and the loop invariant would remain True by default.

Correct answer will be upvoted else Multiple Downvoted. Don't submit random answer. Computer science. anglers have recently gotten back from a fishing excursion. The I-th angler has gotten a fish of weight man-made intelligence. Anglers will flaunt the fish they got to one another. To do as such, they initially pick a request where they show their fish (every angler shows his fish precisely once, in this way, officially, the request for showing fish is a stage of integers from 1 to n). Then, at that point, they show the fish they discovered by the picked request. At the point when an angler shows his fish, he may either become glad, become dismal, or stay content. Assume an angler shows a fish of weight x, and the most extreme load of a formerly shown fish is y (y=0 if that angler is quick to show his fish). Then, at that point: in the event that x≥2y, the angler becomes cheerful; in the event that 2x≤y, the angler becomes miserable; in the event that none of these two…
Control Loops: A high school 1000 students and 1000 lockers. The principal plays the following game: She asks dthe first student to open all the lockers. Shen then asks the second student to close all the even-numbered lockers. The third student is asked to check every third locker. If it is open, the student closes it; if it is closed, the student opens it. The remaining students continue this game . In general, the nth student checks every nth locker. If the locker is open, the student closes it; if it is closed, the student opens it. After all the students have taken their turns, some of the lockers are open and some are closed. Write a program thatprompts the user to enter the number of lockers in a school. After the game is over, the program outputs the number of lockers and the locker numbers of the lockers that are open. Test run your program for the following inputs: 1000, 5000, 10,000. Do you see any pattern developing for the locker numbers that are open in the output?…
Moon effect. Some people believe that the Moon controls their activities.

Assume that the Earth-Moon (center-to-center) distance is 3.82 x 10° m, Earth's radius is 6.37 x 106 m, Moon's mass is 7.36 x 1022 kg, and Earth's mass is 5.98 x 1024 kg. (a) Number 6.89 Units percent (b) Number i 6.8713e-4 Units percent
Broken Cabins Problem Statement: There is an Office consisting of m cabins enumerated from 1 to m. Each cabin is 1 meter long. Sadly, some cabins are broken and need to be repaired. You have an infinitely long repair tape. You want to cut some pieces from the tape and use them to cover all of the broken cabins. To be precise, a piece of tape of integer length t placed at some positions will cover segments 5,5+1-sit-1. You are allowed to cover non-broken cabins, it is also possible that some pieces of tape will overlap. Time is money, so you want to cut at most k continuous pieces of tape to cover all the broken cabins. What is the minimum total length of these pieces? Input Format The first line contains three integers n,m and k(1sns10°, namsloº, Isksn) - the number of broken cabins, the length of the stick and the maximum number of pieces you can use The second line contains n integers bl,b2,bn (Isbism) - the positions of the broken cabins. These integers are given in increasing…
Frog Contest On their way down the river, Jojo and Lili saw two frogs each in position X1and X2. The two frogs are seen jumping happily towards the same direction that is come to Jojo. After watching the two frogs, Jojo and Lili saw that the speed the two frogs are different. The first frog to start jumping from position X1 has a speed of V1, while the second frog that starts to jump from position X2 has a speed of V2. Jojo guess that "YES" both frogs will be in the same position in a certain time T, while Bibiguessing "NO" the two frogs will never be in the same position in timethe. Help Jojo and Lili calculate the frog's movements to determine whether the guess they are right. Input FormatThe first line of input consists of a series of integers namely X1, V1, X2, V2, T.X1 and V1 are the initial position and jump speed per second of the first frog.X2 and V2 are the starting position and jump speed per second of the second frog.T is the second when the frog jumps.

Python tic tac toe. Tic tac toe is a very popular game. Only two players can play at a time. Game Rules Traditionally the first player plays with "X". So you can decide who wants to go with "X" and who wants to go with "O". Only one player can play at a time. If any of the players have filled a square then the other player and the same player cannot override that square. There are only two conditions that may match will be a draw or may win. The player that succeeds in placing three respective marks (X or O) in a horizontal, vertical, or diagonal row wins the game. Winning condition Whoever places three respective marks (X or O) horizontally, vertically, or diagonally will be the winner. Submit your code and screenshots of your code in action. Hints : Have a function that draws the board Have a function that checks position if empty or not Have a function that checks player or won or not expected output:

Count divisibles in range def count_divisibles_in_range(start, end, n): Let us take a breather by tackling a problem simple enough that its solution needs only a couple of conditional statements and some arithmetic, but not even one loop or anything even more fancy. The difficulty is coming up with the conditions that cover all possible cases of this problem exactly right, including all of the potentially tricksy edge and corner cases, without being off-by-one. Given three integers start, end and n so that start <= end, count how many integers between start and end, inclusive, are divisible by n. Sure, you could solve this problem with the list comprehension one-linerreturn len([x for x in range(start, end+1) if x % n == 0]) but of course the automated tester is designed so that anybody trying to solve this problem in such a blunt fashion will only find themselves running out of both time and space! Your code should have no loops at all, but use only integer arithmetic and…

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
Auto-graded programming assignments may use a Unit test to test small parts of a program. Unlike a Compare output test, which evaluates your program's output for specific input values, a Unit test evaluates individual methods to determines if each method: is named correctly and has the correct parameters and return type • calculates and returns the correct value (or prints the correct output) This example lab uses multiple unit tests to test the kilo ToPounds() function. Complete a program that takes a weight in kilograms as input, converts the weight to pounds, and then outputs the weight in pounds. 1 kilogram = 2.204 pounds (lbs). Ex: If the input is: 10 the output is: 22.040000000000003 lbs Note: Your program must define the method public static double kiloToPounds (double kilos) The program below has an error in the kilo ToPounds() method. 1. Try submitting the program for grading (click "Submit mode", then "Submit for grading"). Notice that the first two test cases fail, but the…
