Seneca has just applied conditional formatting and realizes that she has made a mistake. Which action should she take to fix the

erastova [34]

If Seneca has not done anything since the conditional formatting she can undo what her last action was. This is done by either pressing control+Z or by clicking on the undo icon.

If other actions have been done, there are a few more steps that need to be taken in order to clear the formatting. They are:

1. Select the cell or cells whose formatting you want to delete.

2. Display the Home tab of the ribbon.

3. In the Editing group, click Clear | Clear Formats.

Suppose that you need to maintain a collection of data whose contents are fixed- i.e., you need to search for and retrieve exist

Keith_Richards [23]

Answer:

Option a: a sorted array

Explanation:

Since the expectation on the data structure never need to add or delete items, a sorted array is the most desirable option. An array is known for its difficulty to modify the size (either by adding item or removing item). However, this disadvantage would no longer be a concern for this task. This is also the reason, linked list, binary search tree and queue is not a better option here although they offer much greater efficiency to add and remove item from collection.

On another hand, any existing items from the sorted array can be easily retrieved using address indexing and therefore the data query process can be very fast and efficient.

Show how the recursive multiplication algorithm computes XY, where X = 1234 and Y = 4321. Include all recursive computations.

lozanna [386]

Answer:

The result of recursive multiplication algorithm is 5332114 . Here karatsuba algorithm with recursive approach is used to compute XY where X = 1234 and Y = 4321.

Explanation:

The steps for karatsuba algorithm with recursive approach:

base case:

if(X<10) or (Y<10) then multiply X with Y

For example if X is 1 and Y is 2. Then XY = 1*2 = 2

Recursive case:

Now when the above if condition is not true then follow these steps to compute XY

Compute the size of numbers.

Notice that there are 4 digits in X i.e. 1 2 3 4 and a 4 digits in Y i.e. 4 3 2 1

So n = 4

Now divide the numbers in 2 parts as:

n/2 = 4/2 = 2

Since these are decimal numbers so we can write it as:

10^n/2

Now split the digits

X = 1234 is divided into 2 parts as:

12 and 34

Let a represent the first part and b represent the second part of X. So,

a = 12

b = 34

Y = 4321 is divided into 2 parts as:

43 and 21

Let c represent the first part and d represent the second part of Y. So,

c = 43

d = 21

Let multiplication reprsents the karatsuba recursive multiplication algorithm

Now recursively compute products of inputs of size n/2

multiplication (a, c)

multiplication (b, d)

multiplication (add(a, b), add(c, d))

Combine the above 3 products to compute XY

As we know these decimal numbers have base 10 and X and Y are divided into two parts So X can be written as:

X = $10^{\frac{n}{2} }$ a+b

Y can be written as:

Y = $10^{\frac{n}{2} }$ c+d

Now compute XY as:

XY = ( $10^{\frac{n}{2} }$ a+b) ( $10^{\frac{n}{2} }$ c+d)

XY = $10^{\frac{2n}{2} }$ ac + $10^{\frac{n}{2} }$ ad + $10^{\frac{n}{2} }$ bc + bd

= $10^{n}$ ac + $10^{\frac{n}{2} }$ (ad + bc) + bd

Now put the values of n = 4, a = 12, b = 34 , c = 43 and d = 21

= 10⁴ (12*43) + 10² (12*21 + 34*43) + (34*21)

= 10⁴ (516) + 10² (252 + 1462) + 714

= 10000*516 + 100*1714 + 714

= 5160000 + 171400 + 714

XY = 5332114

Hence the karatsuba multiplication algorithm with recursive appraoch computes XY = 5332114

A firm that wanted to enable its employees to use and share data without allowing outsiders to gain access could do so by establ

Bess [88]

Answer:

Intranet

Explanation:

An organization owns a private network which is called an intranet. Private means that the network is accessible to all those employed within the organization, staff of the company.

Intranet exists only within the company and indicates the following.

1. The company establishes its own network inside the company so that the staff of the company can access and exchange information among themselves.

2. The staff can communicate and have discussions on the network.

3. The information is not accessible to outside parties such as customers, stakeholders, and others.

4. The network is not accessible and does not exists for the outside parties.

5. The term intra means inside and net means network.

Intranet leads to the following benefits.

1. The staff can view and exchange information with more ease and comfort and in less time.

2. Faster access to information increases employee output. Employees can perform better and have more time to focus on their work.

3. Communication among the employees is encouraged and made easy. Any one can communicate with every one in the company.

4. More communication leads to better working relationships among the staff. Cooperation and collaboration among the staff is given a boost.

5. Staff can give their input for the type of information to be held in the respository. This serves as the single point of information which enables smooth work flow.

Intranet also has some drawbacks.

The employees can take undue advantage of this communication channel for personal communications and information exchange.

Unproductive communication can only hamper the culture of the workplace.

Guidelines should be enforced to avoid unnecessary communication.

Technologies

Intranet can be implemented by using both local area and wide area networks ( LAN and WAN ). The infrastructure needed for the intranet includes the resources used in both LAN and WAN.
