5.12 LAB: User-Defined Functions: Adjust list by normalizing CORAL LANGUAGE ONLY PLEASE 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. Define a function named getMinimumInt that takes an integer array as a parameter and returns the smallest value. Then write a main program that reads five integers as input, stores the integers in an array, and calls getMinimumInt() with the array as an argument. The main program then outputs the normalized array by subtracting the returned smallest value from all the values in the array. Ex: If the input is: 30 50 10 70 65 function getMinimumInt() returns 10, and the program output is: 20 40 0 60 55 For coding simplicity, follow every output value by a space, even the last one. Your program should define and use a function:Function getMinimumInt(integer array(?) userVals) returns integer minInt…

8.16 LAB: Mileage tracker for a runner C++ Given the MileageTrackerNode class, complete main() to insert nodes into a linked list (using the InsertAfter() function). The first user-input value is the number of nodes in the linked list. Use the PrintNodeData() function to print the entire linked list. DO NOT print the dummy head node. Ex. If the input is: 3 2.2 7/2/18 3.2 7/7/18 4.5 7/16/18 the output is: 2.2, 7/2/18 3.2, 7/7/18 4.5, 7/16/18 Main.cpp #include "MileageTrackerNode.h"#include <string>#include <iostream>using namespace std; int main (int argc, char* argv[]) {// References for MileageTrackerNode objectsMileageTrackerNode* headNode;MileageTrackerNode* currNode;MileageTrackerNode* lastNode; double miles;string date;int i; // Front of nodes listheadNode = new MileageTrackerNode();lastNode = headNode; // TODO: Read in the number of nodes // TODO: For the read in number of nodes, read// in data and insert into the linked list // TODO: Call the…
11.8 LAB: Dates Complete the code to implement the following operations: Complete read_date(): Read an input string representing a date in the format yyyy-mm-dd. Create a date object from the input string. Return the date object. Call read_date() to read four (unique) date objects and store the date objects in a list. Call sorted() to sort the list of date objects, earliest first. Store the sorted dates in a new list. Output the sorted_dates, in the format mm/dd/yy. Hint: Use strftime() to format the date outputs. (See resource below.) Output the number of days between the last two dates in the sorted list as a positive number. Output the date that is 3 weeks from the most recent date in the format "July 4, 1776". Hint: Use timedelta() to set a duration of time for the arithmetic on date objects. (See resources below.)Ex: timedelta(days=50, seconds=27, hours=8, weeks=2) will define a duration of 50 days + 27 seconds + 8 hours + 2 weeks. Output the full name of the day…
solve by Java 11.4 (Maximum element in ArrayList) Write the following method that returns the maximum value in an ArrayList of integers. The method returns null if the list is nul1 or the list size is 0. public static Integer max (ArrayList list) Write a test program that prompts the user to enter a sequence of numbers ending with 0 and invokes this method to return the largest number in the input.
15.14 LAB: Binary search Binary search can be implemented as a recursive algorithm. Each call makes a recursive call on one-half of the list the call received as an argument. Complete the recursive function BinarySearch() with the following specifications: Parameters: a target integer a vector of integers lower and upper bounds within which the recursive call will search Return value: the index within the vector where the target is located -1 if target is not found The template provides the main program and a helper function that reads a vector from input. The algorithm begins by choosing an index midway between the lower and upper bounds. If target == integers.at(index) return index If lower == upper, return -1 to indicate not found Otherwise call the function recursively on half the vector parameter: If integers.at(index) < target, search the vector from index + 1 to upper If integers.at(index) > target, search the vector from lower to index - 1 The vector…

8.13 LAB: Library book sorting Two sorted lists have been created, one implemented using a linked list (LinkedListLibrary linkedListLibrary) and the other implemented using the built-in Vector class (VectorLibrary vectorLibrary). Each list contains 100 books (title, ISBN number, author), sorted in ascending order by ISBN number. Complete main() by inserting a new book into each list using the respective LinkedListLibrary and VectorLibrary InsertSorted() methods and outputting the number of operations the computer must perform to insert the new book. Each InsertSorted() returns the number of operations the computer performs. Ex: If the input is: The Catcher in the Rye 9787543321724 J.D. Salinger the output is: Number of linked list operations: 1 Number of vector operations: 1 Which list do you think will require the most operations? Why? Main.cpp: #include "LinkedListLibrary.h"#include "VectorLibrary.h"#include "BookNode.h"#include "Book.h"#include <fstream>#include…
5.19 LAB: Adjust list by normalizing 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 program, adjust the values by dividing all values by the largest value. The input begins with an integer indicating the number of floating-point values that follow. Assume that the list will always contain less than 20 floating-point values. For coding simplicity, follow every output value by a space, including the last one. And, output each floating-point value with two digits after the decimal point, which can be achieved as follows:printf("%0.2lf ", yourValue); Ex: If the input is: 5 30.0 50.0 10.0 100.0 65.0 the output is: 0.30 0.50 0.10 1.00 0.65 The 5 indicates that there are five floating-point values in the list, namely 30.0, 50.0, 10.0, 100.0, and 65.0. 100.0 is the largest value in the list, so each value is divided by 100.0.…
