Python *4.17 (Game: scissor, rock, paper) Write a program that plays the popular scissor-rock-paper game. (A scissor can cut a paper, a rock can knock a scissor, and a paper canwrap a rock.) The program randomly generates a number 0, 1, or 2 representingscissor, rock, and paper. The program prompts the user to enter a number 0, 1, or2 and displays a message indicating whether the user or the computer wins, loses,or draws. Here are sample runs:scissor (0), rock (1), paper (2): 1 -tnterThe computer is scissor. You are rock. You won.scissor (0), rock (1), paper (2): 2 EnterThe computer is paper. You are paper too. It is a draw.

5.18 Name Lookup The starter code creates a list of first names and a corresponding list of last names. The user is able to enter a first name to look up, which is stored in userInput. Loop through the list of names to find first names which match the user input, and output the corresponding first and last names. For example, if the user searches for 'Amanda', then the program outputs: The following matches were found: Amanda Gates If the user searches for 'Steve', then the program outputs: The following matches were found: Steve Moore Steve Jones If no match is found, then the program outputs: The following matches were found: (none) Hint: use the zip function to simultaneously iterate through the firstName list and lastName list. firstName = ['Joe', 'Amy', 'Sarah', 'Steve', 'Amanda', 'Steve']lastName = ['Johnson', 'Smith', 'Jenkins', 'Moore', 'Gates', 'Jones']
4.31 LAB: Months until payoff (JAVA) Write a program in java that reads a loan amount, payment amount, and interest rate as inputs and outputs the number of payments required until the loan is paid. Interest is added to current balance before a payment is applied. Ex: If current balance is $100.00 and the interest rate is 0.02, the new balance is $102.00 before a payment is applied. All values are doubles. import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); /* Type your code here. */ }}
6.42 PROJECT: Dice Histogram Rolling a single six-sided die produces a random number between 1 and 6 with a uniform distribution. Rolling two dice produces a number between 2 and 12 with a binomial distribution. In this lab you will simulate a number of dice rolls and graph the number of occurrences of each value. 1) Create a function called rollDie() that takes no parameters, and returns a random value between 1 and 6. Do not seed the random number generator in this function. int rollDie() 2) Create a function called initArray() that takes a data array and the size of the array as parameters and fills each element with the summed results of rolling two dice. Do not assume that the data array has been initialized. void initArray(int data[], int size) 3) Create a function called sortArray() that takes an array and the size of the array as parameters, and sorts the array using the sediment sort. void sortArray(int data[], int size) The sediment sort works as follows: start with the…
6.47 LAB: Replacement words (JAVA) Write a program in java that finds word differences between two sentences. The input begins with an integer indicating the number of words in each sentence. The next input line is the first sentence and the following input line is the second sentence. Assume that the two sentences have the same number of words and no more than 20 words each. The program displays word pairs that differ between the two sentences. One pair is displayed per line. Ex: If the input is: 6 Smaller cars get better gas mileage Tiny cars get great fuel economy then the output is: Smaller Tiny better great gas fuel mileage economy Add a method named readSentences to read the input sentences into two String arrays. public static void readSentences(Scanner scnr, String[] sentence1Words, String[] sentence2Words, int wordCount) main() already contains code to read the word count and call readSentences(). Complete main() to display differing word pairs. Code starts here: import…
2.25 (Divisible By 3) Write An Application That Reads An Integer And Determines And Prints Whether It's Divisible By 3 Or Not.
4.27 LAB: Palindrome (JAVA) A palindrome is a word or a phrase that is the same when read both forward and backward. Examples are: "bob," "sees," or "never odd or even" (ignoring spaces). Write a program in java whose input is a word or phrase, and that outputs whether the input is a palindrome. Ex: If the input is: bob the output is: palindrome: bob Ex: If the input is: bobby the output is: not a palindrome: bobby Hint: Start by just handling single-word input, and submit for grading. Once passing single-word test cases, extend the program to handle phrases. If the input is a phrase, remove or ignore spaces. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { /* Type your code here. */ }}
issignment Portion - hand in your wo nce completed "4.2 (Geometry: gneat circle distance) The great circle distance is the distance between two points on the surface of a sphere. Let(x1,y1)and(x2,y2)be the geographical latitude and longitude of two points. The great circle distance between the two points can be computed using the following formula: \[ d=\operatorname{radius} \times \arccos \left(\sin \left(x_{1}\right) \times \sin \left(x_{2}\right)+\cos \left(x_{1}\right) \times \cos \left(x_{2}\right) \times \cos \left(y_{1}-y_{2}\right)\right) \] Write a program that prompts the user to enter the latitude and longitode of two points on the earth in degrees and displays its great circle distance. The average radius of the earth is6,371.01 km. Note you need to convert the degrees into radians using the Math, toRadi ans method since the Java trigonometric methods use radians. The latitude and longitude degrees in the formula are for north and west. Use negative to indicate south and…
5.28 LAB: Toll calculation (EO) Toll roads have different fees based on the time of day and on weekends. Write a method calcToll() that has three parameters: the current hour of time (int), whether the time is morning (boolean), and whether the day is a weekend (boolean). The method returns the correct toll fee (double), based on the chart below. Weekday Tolls Before 7:00 am ($1.15) 7:00 am to 9:59 am ($2.95) 10:00 am to 2:59 pm ($1.90) 3:00 pm to 7:59 pm ($3.95) Starting 8:00 pm ($1.40) Weekend Tolls Before 7:00 am ($1.05) 7:00 am to 7:59 pm ($2.15) Starting 8:00 pm ($1.10) Ex: The method calls below, with the given arguments, will return the following toll fees: calcToll(7, true, false) returns 2.95calcToll(1, false, false) returns 1.90calcToll(3, false, true) returns 2.15calcToll(5, true, true) returns 1.05 code: public class TollCalculation { public double calcToll(int hour, boolean isMorning, boolean isWeekend) { /* Type your code here. */ } public…

3.27 (World Population Growth) World population has grown considerably over the centuries. Continued growth could eventually challenge the limits of breathable air, drinkable water, arable land and other limited resources. There’s evidence that growth has been slowing in recent years and that world population could peak some time this century, then start to decline. For this exercise, research world population growth issues. This is a controversial topic, so be sure to investigate various viewpoints. Get estimates for the current world population and its growth rate. Write a script that calculates world population growth each year for the next 100 years, using the simplifying assumption that the current growth rate will stay constant . Print the results in a table. The first column should display the year from 1 to 100. The second column should display the anticipated world population at the end of that year. The third column should display the numerical increase in the world…
Revise Exercise 6.28 (Craps is a popular dice game played in casinos. Write a program to play a variation of the game, as follows:Roll two dice. Each die has six faces representing values 1, 2, ..., and 6, respectively. Check the sum of the two dice. If the sum is 2, 3, or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (i.e., 4, 5, 6, 8, 9, or 10), a point is established. Continue to roll the dice until either a 7 or the same point value is rolled. If 7 is rolled, you lose. Otherwise, you win.Your program acts as a single player.)to run it 10,000 times and display the number of winning games.
