5.18 LAB: Contains the character (JAVA) Write a program in java that reads an integer, a list of words, and a character. The integer signifies how many words are in the list. The output of the program is every word in the list that contains the character at least once. For coding simplicity, follow each output word by a comma, even the last one. Add a newline to the end of the last output. Assume at least one word in the list will contain the given character. Assume that the list of words will always contain fewer than 20 words. Ex: If the input is: 4 hello zoo sleep drizzle z then the output is: zoo,drizzle, To achieve the above, first read the list into an array. Keep in mind that the character 'a' is not equal to the character 'A'. Code Start: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { /* Type your code here. */ }}
5.23 LAB: Swap ends (JAVA) Write a program in java that reads a list of integers from input and outputs the list with the first and last numbers swapped. The input begins with an integer indicating the number of values that follow. Assume the list contains fewer than 20 integers. Ex: If the input is: 8 1 2 3 4 5 6 7 8 the output is: 8 2 3 4 5 6 7 1 For coding simplicity, follow every output value by a space, including the last one. The output ends with a newline. Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}
5.22 LAB: Array palindrome (JAVA) Write a program in java that reads a list of integers from input and determines if the list is a palindrome (values are identical from first to last and last to first). The input begins with an integer indicating the length of the list that follows. Assume that the list will always contain fewer than 20 integers. Output "yes" if the list is a palindrome and "no" otherwise. The output ends with a newline. Ex: If the input is: 6 1 5 9 9 5 1 the output is: yes Ex: If the input is: 5 1 2 3 4 5 the output is: no Code starts here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { Scanner scnr = new Scanner(System.in); int[] userValues = new int[20]; // List of integers from input /* Type your code here. */ }}
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…
11.13 (Python please) Locate the largest element) Write the following function that returns the location of the largest element in a two-dimensional list: def locateLargest(a): The return value is a one-dimensional list that contains two elements. These two elements indicate the row and column indexes of the largest element in the two-dimensional list. Write a test program that prompts the user to enter a two- dimensional list and displays the location of the largest element in the list. Here is a sample run: Enter the number of rows in the list: 3 (press enter) Enter a row: 23.5 35 2 10 (press enter) Enter a row: 4.5 3 45 3.5 (press enter) Enter a row: 35 44 5.5 11.6 (press enter) The location of the largest element is at (1, 2) (press enter)
15.9.1: LAB: Ticketing service (queue) Given main(), complete the program to add people to a queue. The program should read in a list of people's names including "You" (ending with -1), adding each person to the peopleInQueue queue. Then, remove each person from the queue until "You" is at the head of the queue. Include print statements as shown in the example below. Ex. If the input is: Zadie Smith Tom Sawyer You Louisa Alcott -1 the output is: Welcome to the ticketing service... You are number 3 in the queue. Zadie Smith has purchased a ticket. You are now number 2 Tom Sawyer has purchased a ticket. You are now number 1 You can now purchase your ticket! ------ #include <queue>#include <iostream> using namespace std; int main (int argc, char* argv[]) {string personName = "";int counter = 0;int youPosition; queue<string> peopleInQueue; getline(cin, personName);while (personName != "-1") {// TODO: Add personName to peopleInQueue// determine position of "You"…
5.19 LAB: Elements in a range (JAVA) Write a program in java that first gets a list of integers from input. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain fewer than 20 integers. That list is followed by two more integers representing lower and upper bounds of a range. Your program should output all integers from the list that are within that range (inclusive of the bounds). For coding simplicity, follow each output integer by a comma, even the last one. The output ends with a newline. Ex: If the input is: 5 25 51 0 200 33 0 50 then the output is: 25,0,33, (the bounds are 0-50, so 51 and 200 are out of range and thus not output). To achieve the above, first read the list of integers into an array. Code Start Here: import java.util.Scanner; public class LabProgram { public static void main(String[] args) { /* Type your code here. */ }}

9.27 LAB: Print student roster (EO) Complete the Course class by implementing the printRoster() method, which outputs a list of all students enrolled in a course and also the total number of students in the course. Given classes: Class Course represents a course, which contains an ArrayList of Student objects as a course roster. (Type your code in here) Class Student represents a classroom student, which has three fields: first name, last name, and GPA. (Hint: toString() returns a String representation of the Student object.) Ex: If the following students and their GPA values are added to a course: Henry Cabot with 3.5 GPABrenda Stern with 2.0 GPAJane Flynn with 3.9 GPALynda Robison with 3.2 GPA then the program output is: Henry Cabot (GPA: 3.5) Brenda Stern (GPA: 2.0) Jane Flynn (GPA: 3.9) Lynda Robison (GPA: 3.2) Students: 4

6.28 LAB: Check if array is sorted Use java Programming Write the inOrder() method, which has an array of integers as a parameter, and returns true if the numbers are sorted (in order from low to high) or false otherwise. The program outputs "In order" if the array is sorted, or "Not in order" if the array is not sorted. Ex: If the array passed to the inOrder() method is [5, 6, 7, 8, 3], then the method returns false and the program outputs: Not in order Ex: If the array passed to the inOrder() method is [5, 6, 7, 8 , 10], then the method returns true and the program outputs: In order public class LabProgram {public static boolean inOrder(int [] nums) {/* Type your code here. */ }public static void main(String[] args) {// Test out-of-order example.int [] nums1 = {5, 6, 7, 8, 3};if(inOrder(nums1)){System.out.println("In order");}else{System.out.println("Not in order");}// Test in-order example.int [] nums2 = {5, 6, 7, 8, 10};if(inOrder(nums2)){System.out.println("In…
6.46 LAB: Subtracting list elements from max - methods (JAVA) When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. For this java program, adjust the values by subtracting each value from the maximum. The input begins with an integer indicating the number of integers that follow. Assume that the list will always contain between 1 and 20 integers. Ex: If the input is: 5 30 50 10 70 65 the output is: 40 20 60 0 5 For coding simplicity, follow every output value by a space, even the last one. Your program must define and call a method:public static int getMaxInt(int[] listInts, int listSize) Code starts here: import java.util.Scanner; public class LabProgram { /* Define your method here */ public static void main(String[] args) { /* Type your code here. */ }}
