3. For a sequences: a1, a2, ..., an of n > 2 numbers, write an algorithm that computes a1a2+ a2a3+a3a4 + ... + An-1 an+ana1. Show that this algorithm has time complexity of (f(n)) for some common function f.

What is your mental model of e-mail? How does an e-mail message get from one place to another? Write down your understanding. What differences are there and why? Think about the level of detail (or level of abstraction) that is present in different models.

You are invited to design a national identification number system for U.S. citizens. The ID number should: a. reflect the state, county, and city the person lives in; b. reflect the person’s date of birth; c. take into account the possibility of multiple individuals sharing identical birthday in the same city. Please also EXPLAIN your design of this ID number system with appropriate examples. Merely providing an example is not sufficient.

I wanted them to answer me how to do the bench test of this exercise that I sent :/

you did not answer the question, and I said breif

I'm sorry, but I do not understand this at all. Where in your explanation are the references for H and T? Therefore, what are the answers?

In your own words explain why there is a need for formal methods of evaluating arguments versus simply using the informal methods discussed in Chapter 1. Think about the computers and technology that you use on a daily basis. When you made choices about which technologies to use or incorporate into your life, think about some of the factors or arguments that led you to make those choices? (For example: friend's recommendation, commercials on TV, social media postings, etc.)Write an argument for choosing a specific technology. Include what that specific technology is, and why a person would want to purchase or use it. (This might require you to do a bit of research to learn more about the technology piece you are writing about.) Use the standard argument format for your argument. Which formal method of evaluating an argument (we've discussed two) should be used to determine if your argument above is valid? Explain why would this method work best? Here's the portion where you examine...

What comes to mind when you think about email? Which of these approaches to sending emails is the most efficient? Create a mental list of everything you've picked up thus far. What sets them apart from other things, and why are they so prevalent? What are the different degrees of detail (or abstraction) that may be found in models?

this didnt answer the question at all

What conjures up in your thoughts when you think of an email? What factors into the length of time it takes to send an email from one place to another? Keep a diary to jog your memory of significant events and details. Where do they diverge from one another? Do you know the level of detail (or abstractness) that each model has?

Whose hands did The Glass Cage's words rest in?

I was not looking for code, but rather an explanation.

What mental model do you have of e-mail? How is an e-mail message sent from one location to another? Make a note of your comprehension. What distinctions exist and why? Consider the degree of detail (or abstraction) contained in various models.
