A high school has 1000 students and 1000 lockers, one locker for each student. On the first day ofschool, the principal plays the following game: She asks the first student to open all the lockers. Shethen asks the second student to close all the even-numbered lockers. The third student is asked tocheck every third locker. If it is open, the student closes it; if it is closed, the student opens it. Thefourth student is asked to check every fourth 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 checksevery nth locker. If it is open, the student closes it; if it is closed, the student opens it. After all thestudents have taken turns, some of the lockers are open and some are closed.The program below, when ran, will prompt the user to enter the number of lockers in the school.After the game is over, the program will output the number of lockers and the lockers numbers ofthe lockers that are open.

Control structures

Control structures are block of statements that analyze the value of variables and determine the flow of execution based on those values. When a program is running, the CPU executes the code line by line. After sometime, the program reaches the point where it has to make a decision on whether it has to go to another part of the code or repeat execution of certain part of the code. These results affect the flow of the program's code and these are called control structures.

Switch Statement

The switch statement is a key feature that is used by the programmers a lot in the world of programming and coding, as well as in information technology in general. The switch statement is a selection control mechanism that allows the variable value to change the order of the individual statements in the software execution via search.

A high school has 1000 students and 1000 lockers, one locker for each student. On the first day of
school, the principal plays the following game: She asks the first student to open all the lockers. She
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
fourth student is asked to check every fourth 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 it is open, the student closes it; if it is closed, the student opens it. After all the
students have taken turns, some of the lockers are open and some are closed.
The program below, when ran, will prompt the user to enter the number of lockers in the school.
After the game is over, the program will output the number of lockers and the lockers numbers of
the lockers that are open. However, the statements are in the wrong order, and there are some
bugs in this program. Rearrange the statements and also find and remove the bugs so that the
program can run properly. RENAME THE CLASS TO

The program below, while has the correct output, doesn't follow the game's logic at all.
* Instead, it follows a certain pattern that's present in the game.

3rd, 4th, Sth, 1eth, 20th, 25th, seth, and 100th student. Coincidentally, these are also the positive
divisors of 100. Similarly, the 30th locker is visited by the students whose numbers are 1, 2, 3, 5, 6

Children often play a memory game in which a deck of cards containing matching pairs is used. The cardsare shuffled and placed face down on a table. The players then take turns and select two cards at a time.If both cards match, they are left face up; otherwise, the cards are placed face down at the same positions.Once the players see the selected pair of cards and if the cards do not match, then they can memorize thecards and use their memory to select the next pair of cards. The game continues until all the cards areface up. Write a program to play the memory game. Use a two-dimensional array of 4 rows and 4 columnsfor a deck of 16 cards with 8 matching pairs. You can use numbers 1 to 8 to mark the cards. (If you use a6 by 6 array, then you will need 18 matching pairs, and so on.) Use random number generators torandomly store the pairs in the array. Use appropriate functions in your program, and the main programshould be merely a call to functions. I need to figure out how to do…
The game is played in the magic maze, as shown below. The squares are flaming lava pools. If you try to cross them you will die. The grid lines are passageways and are safe to travel in. You can start at any location on the grid but must travel in the passageways. You may travel as far as you want in any direction, but once you turn, you must repeat that distance and you may only make left turns. You may not reverse direction inside the tight passageways. You must end up at the same spot you started at. If you successful, then you gain a magic coin, which automatically appears. You can start over again and again in a different or same starting spot and earn new magic coins, but the routes you take must differ somehow for each magic coin. That is, no magic coins for the exact same route as previously done. If the route varies in any way (perhaps it is the same starting location and ending location as a previous route, but longer), it will earn a new magic coin. Mad Madame Mim has…
It is given 12 balls that are all the same weight except for one that is heavier or lighter. Additionally, it is provided with a two-pan balance. In each scenario, the balance is used. You may place any number of the 12 balls on the left pan and the same number on the right pan and press a button to begin weighing; three alternative results exist: the weights are equal, the balls on the left are heavier, or the balls on the left are lighter. Develop a technique for determining which ball is the odd one out and whether it is heavier or lighter than the others using the fewest feasible uses of the balance. Solve the weighing issue for the situation of 39 balls, one of which is known to be strange.
2) scrooge.py Scrooge McDuck is letting you into his vault full of pennies, nickels, dimes and quarters. He will let you play the following game: you can pick 8 coins at random, and if they sum to at least a dollar, you win, and can keep your money! But if you lose, you don't get to keep the money, AND have to pay Scrooge a dollar. (Each coin you pick is equally likely to be a penny, nickel, dime, or quarter.) Your job: using a simulation, estimate 1. the probability that you win (meaning your coins sum to more than a dollar), and 2. if you play this game over and over, the average amount you will win (where the amount you win in a game could be negative). Here is a bit more direction: you should simulate 100,000 plays of this game. Each simulated play should involve picking 8 different random numbers - each one should be .01, .05, .10, or .25, with each value equally likely - which represent the 8 coins being chosen; these should be summed each time. As you proceed through these…

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:
