*****************PLEASE GIVE THE CODE IN RACKET PROGRAMMING ONLY AND MAKE SURE THE CODE RUNS ON WESCHEME IDE***************

Write a recursive Racket function "sum-diff" that takes two lists of integers that are the same length and evaluates to an integer. The resulting integer should be the sum of the absolute value of the differences between each pair of integers with the same index in the two lists. For example (sum-diff '(-1 -2 -3) '(1 2 3)) should evaluate to 12 because the absolute value of the differences between (-1 and 1), (-2 and 2) and (-3 and 3) are 2, 4, and 6, and 2+4+6=12. Note: (abs n) evaluates to the absolute value of n. Also, if the lists are empty the sum should be 0

Write a C program that demonstrate tree traversal.

A. first is to ask the user to enter data

B. ask how many nodes

THIS IS JUST A SAMPLE. PLEASE ANSWER IT IN COMPLETE CODE.

See for the sample output.

Sample Output:

How many node do you have in your tree : 5

Enter root: 20
if you want to add to the left press 0 otherwise press 1
answer: 0
Enter next node: 10
if you want to add to the left press 0 otherwise press 1
answer: 0
Enter next node: 8
if you want to add to the left press 0 otherwise press 1
answer: 0
Enter next node: 15

Give an algorithm for reversing a queue Q. Only following standard operations are allowed on queue. 1. enqueue(x) : Add an item x to rear of queue. 2. dequeue() : Remove an item from front of queue. 3. empty() : Checks if a queue is empty or not.. (Hint: you can use LinkedList, Stacks, and Queues from the java data collection)

OUTPUT Examples: Input : Q = [10, 20, 30, 40, 50, 60, 70, 80, 90, 100] Output :Q = [100, 90, 80, 70, 60, 50, 40, 30, 20, 10] Input :[1, 2, 3, 4, 5] Output :[5, 4, 3, 2, 1]

(Machine learning Neural Network) Consider a regression Multilayer Perceptron (MLP) that uses identity activation functions for all neurons. A data scientist trains the neural network to minimize the MSE(Mean Squared Error), and he observes a much smaller training set MSE for the MLP as compared to that for OLS (Oridinary Least Squares). Is this possible? Justify your answer.

CMIS 320 Project 1
Write a justification paper, of at least 2 pages, to your boss explaining how a relational database solution can be applied to a current business problem or area for improvement. Assume that your boss knows nothing about relational database theory. The goal of this paper is to obtain your boss's approval to proceed with your stated project. Do not focus on technical aspects of a database management system. Focus on how the information will be captured, manipulated, managed, and shared, and the value the database brings to the organization. Include brief examples of how other industries (both domestic and international) have successfully used relational databases to increase efficiency.

Homework 5: Lists

Please show code in Pycharm

The task is to create the following three functions to demonstrate techniques for working with lists:

1. greatestPair(x), which accepts a list of numbers x and returns the index position of the greatest adjacent pair. For example, if the list [4, 3, 8, 0] was passed to your function, it would return 1, as that the values 3 and 8 form the greatest adjacent pair in the list. Your function should return None if passed an empty list.
2. isSorted(x) that takes a list of numbers and returns True if the list is sorted (either smallest-first or largest-first) and False otherwise. Your function should return None if passed an empty list.
3. intersection(x,y) that takes two lists x and y as parameters and returns a new list containing the intersection of the two parameters (all elements that are common to both x and y). The returned list should not contain duplicate values.

Discuss the advantages and disadvantages of using DHCP.

write code using Arduino to display the digits of pi(π) to the 20th decimal point on a 7-segment display. You code should include functions for all the digits, and your loop( ) should only call the functions to display the numbers. Delay 500ms between each number. Use macro definitions for the individual LED's.

One customer has sent you the following email to initiate a project.

“I need to make a report program manager using the internet data from internet system. I only need the data related to signal strength and customer satisfaction rating. I need to be able to sort this by state.” What are the followup questions, and what research you would do before meeting the program manager with the customer what information would you add on the requirement document.

This question is about providing game logic for the game of craps we developed its shell in class. At the end of the game, you should ask the user if wants to play another game, if so, make it happen. Otherwise, quit

**Provide the working output of this game and the picture of the output. **

This is an implementation of the famous 'Game of Chance' called 'craps'.
It is a dice game. A player rolls 2 dice. Each die has six faces: 1, 2, 3, 4, 5, 6.
Based on the values on the dice, we play the game until a player wins or loses.
You add the values of the dice's face.
1) If the sum is 7 or 11 on the first roll, the player wins.
2) If the sum is 2, 3, or 12 on the first roll, the player loses ( or the 'house' wins)
3) If the sum is 4, 5, 6, 8, 9, or 10 on the first roll, then that sum becomes the player's 'point'.
4)To win, the player must continue rolling the dice until he/she 'make the point'.
5)If the player rolls a 7 he/she loses.
