- Please look at attached photos. It needs to pass all of the simulations. Thanks in advance Cryptography is the practice of encryption. Information Security uses cryptography techniques to encrypt and decrypt data. A simple encryption method might take plaintext and mix up the letters using some predetermined pattern and then use that pattern to decrypt the data for reading. Ciphers are the algorithms used to put the data into its secret pattern and then systematically decrypt it for reading. This script is going to use a famous simple cipher called the Caesar Cipher. It is a substitution cipher where each letter in the text is 'shifted' in a certain number of places. It uses the alphabet as the primary pattern and then based on the shift number, it would shift all the letters and replace the alphabet with our pattern. For example, if our shift number was 3, then A would be replaced with D, if we performed a right shift. As an example: Text = "THE CAT IS VISIBLE AT MIDNIGHT" Ciphertext…Return the Remainder from Two Numbers There is a single operator in JavaScript, capable of providing the remainder of a division operation. Two numbers are passed as parameters. The first parameter divided by the second parameter will have a remainder, possibly zero. Return that value. Examples remainder(1, 3) → 1 remainder(3, 4) → 3 remainder(-9, 45) → -9 remainder(5, 5) → 0A boatman, a wolf, a sheep, and a cabbage are on the bank of a river. They have a small boat that is capable of carrying the boatman and at most one other animal/item with him. However, if left alone by the boatman, the wolf can eat the sheep, and the sheep can eat the cabbage. How can all four be moved safely to the opposite bank of the river? Here is a nice visualization of the whole process in the original game. Disclaimer: writers, testers and CodeChef are not related to this link. This leads to a more general problem. If there are other groups of animals/items with the boatman, is it possible to move them all to the opposite bank of the river in such a way that nobody/nothing gets eaten? We will give you the number of animals/items (not including the boatman). Moreover, we will give you all a list of pairs of the form "X Y" where the X-th animalitem will be eaten by the Y-th one if they are both on the opposite bank to the boatman. You are to determine whether it is possible to…
- Let's begin with a lesson in roulette. Roulette is a casino game that involves spinning a ball on a wheel that is marked with numbered squares that are red, black, or green. Half of the numbers 1–36 are colored red and half are black and the numbers 0 and 00 are green. Each number occurs only once on the wheel. We can make many different types of bets, but two of the most common are to bet on a single number (1–36) or to bet on a color (either red or black). These will be the two bets we will consider in this project. After all players place their bets on the table, the wheel is spun and the ball tossed onto the wheel. The pocket in which the ball lands on the wheel determines the winning number and color. The ball can land on only one color and number at a time. We begin by placing a bet on a number between 1 and 36. This bet pays 36 to 1 in most casinos, which means we will be paid $36 for each $1 we bet on the winning number. If we lose, we simply lose whatever amount of money we…Let's begin with a lesson in roulette.

There will be some bad ones (say, not that tasty). Your task is to identify these bad candies from n candies and discard them. Fortunately, you have a device to help you with this. If you put a batch of candies in the device, as long as there exists any bad candy, the device will return “BAD!" to you. Otherwise (i.e., all the candies are good) it returns "GOOD!". Of course, if you put only one candy into the device, you can directly know if it is good or bad. However, every time you use the device, you need to pay 1 dollar, no matter how many candies you put in the tested batch. You want to use the device fewer times to save money. Note that the device will not tell you how many bad candies are there in the tested batch or which ones are bad, it only tells you whether there's any bad candy. Also, you don't know in advance how many bad candies are there in the n candies. You can put all the…
- Java problem. While out on a standard run we notice that our radar is picking up someone following us. In the hopes of losing them, we look for a nearby debris field to hide in. We notice one not too far away, but we need to make sure that we can get to the middle of the debris field to be properly hidden. Our radar shows the debris field in 2D, so we can visually check if we can make it to the center, but that takes too long. We want a program that will let us know if there is a path from the outside of the debris field to the center. In order to solve this problem, we must think recursively. Create a recursive algorithm that determines if a path exists from the outside of the debris field to the center. The debris field is always square (n by n) and n will always be greater than 1, and always odd. You can enter the debris field from any of the outside spaces, and you simply need to return true if a path exists, and false if a path does not exist. For movement you can only go up,…We are creating an ATM class in Java. I need some more examples for the assignment we are working on. How would I set an account number with a pin?I also need the program to allow only 3 total attempts to enter the correct pin before closing.If the correct pin is inserted, list the day&time and a menu that includes Withdraw, Deposit, Balance, and Quit.in java using import java.util.Scanner; Bowling involves 10 frames. Each frame starts with 10 pins. The bowler has two throws to knock all 10 pins down. The total score is the sum of pins knocked down, with some special rules. For the first 9 frames: If all 10 pins are knocked down on a frame's first throw (a "strike"), that frame's score is the previous frame plus 10 plus the next two throws. (No second throw is taken). If all 10 pins are knocked down after a frame's second throw (a "spare"), that frame's score is the previous frame plus 10 plus the next throw. In the 10th frame, if the bowler's first throw is a strike, or the first two throws yields a spare, the bowler gets a third throw. The 10th frame's score is the previous frame's score plus the pins knocked down in the 10th frame's two or three throws. Given integers represents all throws for a game, output on one line each frame's score followed by a space (and end with a newline). Note that the number of throws may be as…
- Implement a java project to help in the study analysis with the following steps:• Read from the user the number of cities (minimum 6 cities.)• For each city: city name and the number of persons (minimum 10 persons) are entered.• For each person in a city: mass and height should be entered, BMI and BMI category have to becomputed and printed.• For each city, the number of persons and percent ratio in each BMI category should be computedand printedWrite a program to build a calculator. Instead of a typical calculator which reads in-order expressions and evaluates them, build a calculator that takes in numbers and assigns the operations to yield the highest value expression. The current operations on the calculator only handle pairs of parentheses, and the operators for addition, subtraction, multiplication, and division. The calculator can rearrange the numbers if it helps find the optimal value. For example, the list:4.0 5.0 3.0 2.0 1.0using the calculator should find the optimal expression yielding the maximum value to be:4.0 * 5.0 * 3.0 * (2.0 + 1.0) = 180Input from the keyboard a list of up to 10 floating-point values from-100000.0to100000.0. Output to the screen a single floating-point value rounded to two decimal places representing the highest value expression that the calculator could create by inserting the symbols( ) + - * /into the given expression. Assume at least one number in the list and only the operators listed…Implement the one-time pad encryption scheme in Microsoft Excel. Your worksheet should look as follows: For Encryption: - Have the message occupy adjacent cells in one row, with one bit of the message in each cell. Align the key (the one-time pad) with the message in the next row. Note that the key should be of the same length as the message. In the next row, enter a formula that computes the ciphertext. Decryption is similar: - Have the ciphertext occupy adjacent cells in one row, with one bit of the ciphertext in each cell. Align the key (the one-time pad) with the ciphertxt in the next row. Note that the key should be of the same length as the ciphertext. In the next row, enter a formula that computes the plaintext (message). .
