Answer:

d. involves analyzing end-user business requirements in order to refine project goals

Explanation:

In the software development life cycle, the implementation stage is the stage where the computer programmers begin the actual coding of the application required by the end-user. At this stage, the developer takes into account the needs and specifications of the customer.

For example, if the end-user wants a software application that can track payment records, the researcher at this stage begins using the right software to code programs that can effect this function.

What exactly is change management?

Change management is the process of developing and implementing effective change strategies in businesses and organizations.

Examining the reasons for change, implementing changes, and assisting people in adapting to these changes are all part of it. This could include reorganizing the workforce, implementing new technology, lowering costs, increasing profits, or a combination of these to achieve a specific goal.

Greedy Algorithm Design

Alik [6]

Answer:

The algorithm is as follows:

1. Start

2. Get the number of items (n)

3. Get the current price of the n items (a1, a2..... an)

4. Get the possible hiked price of the n items (b1, b2..... bn)

5. Calculate the difference between the current and hiked prices for each item i.e. $d_i = b_i - a_i$

6. Sort the differences in descending order (i.e. from the greatest to the least)

7. Buy items in this order of difference

8. Stop

Explanation:

The algorithm is self-explanatory; however, what it does is that:

It takes a list of the current price of items (say list a)

E.g: $a = [100, 150, 160]$

Then take a list of the hiked price of the items (say list b)

E.g: $b = [110, 180, 165]$

Next, it calculates the difference (d) between corresponding prices $d_i = b_i - a_i$

$d = [(110 - 100),(180-150),(165-160)]$

$d = [10,30,5]$

Sort the difference from greatest to lowest (as the difference is sorted, lists a and b are also sorted)

$d = [30,10,5]$

$a = [150, 100, 160]$

$b = [180, 110, 165]$

If there is no hike up to item k, the couple would have saved (i = 1 to d[k-1])

Assume k = 3

The couple would have saved for 2 item

$Savings = d[1] + d[2]$

$Savings = 30 +10$

$Savings = 40$

The saved amount will then be added to the kth item in list a i.e. a[k](in this case k = 3) in order to buy b[k]

Using the assumed value of k

$a[k] = a[3]$

$a[3] = 160$

$b[3] = 165$

Add the saved amount (40) to a[3]

$New\ Amount = 40 + 160$

$New\ Amount = 200$

This new amount can then be used to buy b[3] i.e. 165, then they save the change for subsequent items

Murrr4er [49]

Answer:

Data Frame

A data frame is used for storing data tables. It is a list of vectors of equal length. For example, the following variable df is a data frame containing three vectors n, s, b.

> n = c(2, 3, 5)

> s = c("aa", "bb", "cc")

> b = c(TRUE, FALSE, TRUE)

> df = data.frame(n, s, b) # df is a data frame

Built-in Data Frame

We use built-in data frames in R for our tutorials. For example, here is a built-in data frame in R, called mtcars.

The top line of the table, called the header, contains the column names. Each horizontal line afterward denotes a data row, which begins with the name of the row, and then followed by the actual data. Each data member of a row is called a cell.

To retrieve data in a cell, we would enter its row and column coordinates in the single square bracket "[]" operator. The two coordinates are separated by a comma. In other words, the coordinates begins with row position, then followed by a comma, and ends with the column position. The order is important.
