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. */ }}
5.16 LAB: Adjust list by normalizing (JAVA) When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This adjustment can be done by normalizing to values between 0 and 1, or throwing away outliers. For this java 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 fewer than 20 floating-point values. Output each floating-point value with two digits after the decimal point, which can be achieved as follows:System.out.printf("%.2f", 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. For coding simplicity, follow every output value by a…

4.10 LAB: All permutations of names Write a program that lists all ways people can line up for a photo (all permutations of a list of strings). The program will read a list of one word names, then use a recursive function to create and output all possible orderings of those names separated by a comma, one ordering per line. When the input is: Julia Lucas Mia then the output is (must match the below ordering): Julia, Lucas, Mia Julia, Mia, Lucas Lucas, Julia, Mia Lucas, Mia, Julia Mia, Julia, Lucas Mia, Lucas, Julia def print_all_permutations(permList, nameList): # TODO: Implement method to create and output all permutations of the list of names. if __name__ == "__main__": nameList = input().split(' ') permList = [] print_all_permutations(permList, nameList)
1. Recursion & List processing Write a recursive function flatten that takes a list as an argument and returns the flat version of that list. For example, (flatten '(a (b c) d)) -> (a b c d) (flatten '(((a)) (b (c)) d)-> (a b c d)
(C Language) The Fibonacci sequence begins with 0 and then 1 follows. All subsequent values are the sum of the previous two, for example: 0, 1, 1, 2, 3, 5, 8, 13. Complete the Fibonacci() function, which takes in an index, n, and returns the nth value in the sequence. Any negative index values should return -1.

Linked List Write a DETAILED algorithm length to count the number of nodes in a singly linked list p, where p points to the first node in the list. The last node has link field NULL. Assume that each node has two fields: data and link. Account for the range of all possible linked list lengths. Needs to be in detailed and code in C PROGRAM would be helpful!
