Write a program to ask three options to the user and continue until user selects option 3.
The first two options prompt a user to enter a string of numbers separated by spaces which is a 2by2 matrix. Do addition and subtraction on the input matrices when user selects 1 and 2.
You must write functions for matrix addition, subtraction and print. You may use the following function str_to_mlist to convert string to a list.
code example is given:
def str_to_mlist(m_str):
"""Converts a string separated by spaces to a list
Parameters
----------
m_str : str, required
Input string separated by spaces
Returns
-------
list
Numbers
"""
return m_str.split()
A sample run of the code looks like this:
Enter an option
1.Add two matrices
2.Subtract two matrices
3.Quit

Enter four numbers separated by spaces and press enter:3 4 -10

Determine the running time of each of the algorithms below. For questions 2a. and 2b., you may determine the running time line-by-line (see Lecture 2, slide No. 8). For questions 2c – 2f, you may determine the running time by focusing on the basic operation of the algorithm.
a,sum = 0; for (i=1; i<=n; i++) sum += n;
b. Algorithm maxVal (numbers, n) currentVal ← numbers [0] for i ← 1 to n − 1 do if numbers [i] > currentVal then currentVal ←A[i] { increment counter i } return currentVal
c. Algorithm prefix1(X, n) //Input array X of n integers //Output array A of prefix averages of X A ← new array of n integers for i ← 0 to n − 1 do s ←X[0] for j ← 1 to i do s ←s + X[j] A[i] ←s / (i + 1) return A
d. Algorithm prefix2(X, n) //Input array X of n integers //Output array A of prefix averages of X A ← new array of n integers s ← 0 for i ← 0 to n − 1 do s ←s + X[i] A[i] ←s / (i + 1) return A
e. Algorithm SumTripleArray(X, n) //Input triple array X[][][] of n by n by n integers //Output sum of elements of X s ← 0 for i ← 0 to n − 1 do for j ← 0 to n − 1 do for k ← 0 to n − 1 do s ←s + X[i][j][k] return s
f. sum = 0; for( i = 0; i < n; i++) for( j = 0; j < n * n; j++) sum++;

Remember the brand is wrapped around the product and products can
be tangible or intangible.
a) Describe fully the services provided by Facebook Inc. to
consumers (B2C) and businesses (B2B).
Explain why Facebook Inc. product is either tangible or
intangible?

Keep a record of your use of the mass media-television, internet, facebook, gaming, movies, etc.-including your reason for using these sources. Then take the role of a sociologist and write about how you might have been socialized by the media you used. What norms and values were you exposed to? How did they affect you? Which other agents of socialization (besides media) influenced your use of mass media (did peers or other groups/entities entice you?

Below is a short list provided by DuPont of common ethical issues in the workplace. Choose at least three issues and explain what would be a “wrong” expression of that scenario and solve it with a “right” way to solve that scenario.
For example: Mercedes claimed her hair appointment as a company expense. A “wrong” way to handle the situation would be to approve the expense and not confront the employee on the unrelated business expense. A “right” way to solve the issue would be to meet with Mercedes one-on-one to hear her reasoning in qualifying it as an expense. If the expense did not pertain to her work duties, then politely explaining how hair appointments are not considered business-related expenses and she will not be reimbursed for the expense.

1- Buffering & Spooling.
2- Synchronous & Asynchronous I/O.
3- CPU-bound & I/O-bound jobs.
4- Multiprogramming & Timesharing.
5- Logical & Physical addresses.
6- User & Monitor modes in Operating System.
[2] (i) Define Timesharing.
(ii) In a one processor system, there is an interrupt clock which is set to a “time slice Q”, that is, every Q an interrupt occurs to stop the process. There is only one I/O device in the system which is interrupted when the process needs an I/O. There are 3 processes A, B, C.
Process A executes an I/O interrupt every T units of time.
Process B executes an I/O interrupt every 2T units of time.
Process C executes an I/O interrupt every 3T units of time.
(a) Which of the above processes will benefit the most and which is not when Q = T.
Explain your answer
(b) Which of the above processes will benefit the most and which is not when Q = 2T.

Analyse the security of Lamport’s OLP algorithm with the properties of hash function
In: Computer Science
On January 1, NewTune Company exchanges 17,360 shares of its common stock for all of the outstanding shares of On-the-Go, Inc. Each of NewTune’s shares has a $4 par value and a $50 fair value. The fair value of the stock exchanged in the acquisition was considered equal to On-the-Go’s fair value. NewTune also paid $44,650 in stock registration and issuance costs in connection with the merger.
Several of On-the-Go’s accounts’ fair values differ from their book values on this date (credit balances in parentheses):
| Book Values | Fair Values | |||||
| Receivables | $ | 44,250 | $ | 41,300 | ||
| Trademarks | 117,250 | 277,750 | ||||
| Record music catalog | 66,000 | 186,750 | ||||
| In-process research and development | 0 | 261,000 | ||||
| Notes payable | (54,750 | ) | (48,350 | ) | ||
Precombination book values for the two companies are as follows:
| NewTune | On-the-Go | |||||
| Cash | $ | 62,000 | $ | 50,250 | ||
| Receivables | 125,000 | 44,250 | ||||
| Trademarks | 441,000 | 117,250 | ||||
| Record music catalog | 873,000 | 66,000 | ||||
| Equipment (net) | 344,000 | 108,000 | ||||
| Total Assets | $ | 1,845,000 | $ | 385,750 | ||
| Accounts payable | $ | (150,000 | ) | $ | (43,500 | ) |
| Notes payable | (378,000 | ) | (54,750 | ) | ||
| Common stock | (400,000 | ) | (50,000 | ) | ||
| Additional paid-in capital | (30,000 | ) | (30,000 | ) | ||
| Retained earnings | (887,000 | ) | (207,500 | ) | ||
| Total liabilities and equities | $ | (1,845,000 | ) | $ | (385,750 | ) |
1. Assume that this combination is a statutory merger so that On-the-Go’s accounts will be transferred to the records of NewTune. On-the-Go will be dissolved and will no longer exist as a legal entity. Prepare a postcombination balance sheet for NewTune as of the acquisition date.

2. Assume that no dissolution takes place in connection with this combination. Rather, both companies retain their separate legal identities. Prepare a worksheet to consolidate the two companies as of the combination date.

Explain Maslow’s hierarchy of needs. What does it tell us about employee motivation? Cite an example of what a company does to provide motivation for each of the levels within the hierarchy?
I believe having a diverse workforce is very valuable,as diversity is much needed in today's world.When in business you have people to be able to meet all needs which may require language, nationality, socioeconomic status, gender, religion, or sexual orientation.Is it a challenge for human resource managers yes.Having to learn and understand everyone's background and coming to an understanding with what works best for everyone to work together.I believe these challenges are overcome by open door policies and communication.If you are interviewing probably and knowing your teams weak and strong needs you are able to bring in the right fit to make everything balance in the work place.I also believe open door leaves room for employees and employers to discuss things properly without confrontation and understanding core values.
What is your reply about that post?
