The next structure you will investigate is the Hash table and its methods implemented in pseudo code when linked lists are used to handle collisions. 

The task this week is to complete the pseudo code for the following hash table operations: 

1. Insert
2. Remove 

Assume Hashtable is a simple array of size 8, with indices 0..7. Numeric keys are mapped by a Hashfunction that gives the mod(8,n) value for any key “n” yielding the Hashtable index for that key (0..7). A Hashtable entry is null unless a key exists with that index as its hashed index; if so, the Hashtable entry points to the first node of a linked list of keys with that hash index. The last node on this linked list has a null reference for the next referenced node. Assume the occurrence of a linked list node is represented by the object “Node” and its “Data” and “NextRef” attributes.

Week 2 Deliverables:

• 1 pseudo code implementation of each Hash table operation: Insert and Remove
• Fully documented pseudo code.
• Add the completed pseudo code and the output to the Key Assignment template Section 2: Hashing, Heaps and Trees.
• Name the document “IT265__IP2.doc.” 

Sort algorithms have many trade-offs, in-fact even the sorted output sequences might differ. 

Part 1: Your tasks for this assignment are the following:

1. Identify at least five (5) algorithm differences that might be considered when choosing a sort algorithm. 
2. Offer examples of related sorts with the discussion of each difference considered. 

Part 2: Rationalize:

You have formed a hypothesis that Big O analysis is not appropriate for comparing different sort algorithms, but rather for comparing the performance of a given sort algorithm as the number of sort keys change. (Hint: consider locality differences among sorts).

Week 3 Deliverables:

• 5 fully documented differences among sorting algorithms.
• Support the differences with Sort algorithms that exemplify the related characteristics.
• Generate a summary of Sort differences.
• Include the Big O critique.
• Name the document “IT265__IP3.doc.”

Key Assignment Draft: Include session changes

The first two Individual Projects used linked lists for stacks, queues, and hashing implementations. With this task, searching performance with linked lists will be addressed. 

Part 1: Your tasks for this assignment are the following:

1. Discuss the use of a binary tree when searching for keys in an array.
2. Discuss the use of a binary tree when searching for keys in a linked list. 

Part 2: Complete the following program:

1. Describe a linked list structure to support binary searching.
2. Create pseudo code to describe a binary search with this linked list variation. 

Week 4 Deliverables:

• Summary of binary search with an array.
• Summary of binary search with a linked list.
• 1 fully documented pseudo code implementation of a linked list useful for binary searches. 

Part 3: Key Assignment Draft: 

Once you have completed this section, submit the pseudocode and summary of binary searches from all of the following in your Key Assignment template:

• Section 1: Lists, Stacks, and Queues
• Section 2: Heaps and Trees
• Section 3: Sorting Algorithms
• Section 4: Searching 

Name the document “IT265_yourname_IP4.doc.”

 A Usability Evaluation examines the way users interact with products and services in order to achieve a goal. Oftentimes, there are measures that are tied to those goals that are quantified. Academic literature has a robust catalog of research on studies that examine various perspectives that explore user attitudes and experiences. Such attitudes and experiences include:

• System Quality and Usability

Remember, usability is not one-dimensional. It is a complex system of properties. That integrates many factors. It is subjective from user to user. For this assignment, you are asked to explore one of these topics. You are to conduct an analytical research review of the assigned usability category/dimension above. Write a paper that consists of the following:

• Abstract
• Title Page
• Introduction
• Literature Review of Term
• Conclusion

Considerations:

• Must provide a minimum of seven sources that analyze the term and its meaning
• Must analyze and compare the term and how it was evaluated by the authors/scholars in each study
• Must evaluate the study method used to complete the analysis.
• Identify any unique similarities or differences across each study.
• Define your own term based on your understanding of the literature you’ve evaluated.
• Explain how you derive this definition.
• Qualify/quantify the definition by explaining how many sources you used to come up with this definition.
• Make Recommendations of Additional Ideas For Future Literature Review Consideration
• The paper should be a minimum of 10 pages. This does not include the cover page, abstract, or citations. You must use the APA format throughout the entire paper.

Module 03 Discussion – Recommendations for Life Stages

A person’s nutrient needs may change for a variety of reasons, but the most influential is stage-of-life. In this discussion, you will examine two stages of life chosen from the following:

• Infancy
• Childhood
• Adolescence
• Adulthood
• Older adulthood
• Pregnancy and Lactation

For your initial post, address the following:

1. Identify the two life stages of life you will discuss and list their names in the title of your initial post.
2. Research and describe the current nutrient recommendations for the life stages you selected.
3. Suggest foods that would be beneficial for each of the life stages you selected and explain why.

Review the posts made by your classmates, and reply to at least two. Suggest at least one additional food to consider for each of the life stages they discussed. Provide the rationale supporting your recommendations.

Should you wish to provide your initial or response posts with data or research found, be sure to utilize proper APA formatting and cite your resources.

 What is AI’s Natural Language processing. What does it involved and provide some examples of it.
Provide examples and present your written findings. You must write a 3-page essay in APA format. You must include 3 scholarly reviewed references that are DIRECTLY related to the subject.

Answer the following questions based on this scenario.

Problem: Write a program that reads 10 username and password values into parallel arrays. After the arrays have been loaded, the program should behave like a login screen, prompting for a username and a password. Based on the data read and stored in the arrays, the program should respond appropriately with one of three output messages: “Username not found.”, “Username and password does not match.” or “Access granted.”

Question 1: Would you write this program asking a user to enter the usernames and passwords or would you use a file that contains all the username and passwords as input?  Explain why you would choose one over the other.  

Question 2: Will your answer remain the same if the number of username and password values change to 40, and why?

The assignment file is uploaded below. Please answer all the questions carefully.
