Answer:

The answer to this question is given below in the explanation section.

Explanation:

First, we need to convert these hexadecimal numbers into decimal numbers, then we can easily identify which one is the lowest hexadecimal.

The hexadecimal numbers are F2, 81, 3C, and 39.

F2 = (F2)₁₆ = (15 × 16¹) + (2 × 16⁰) = (242)₁₀

81 = (81)₁₆ = (8 × 16¹) + (1 × 16⁰) = (129)₁₀

3C = (3C)₁₆ = (3 × 16¹) + (12 × 16⁰) = (60)₁₀

39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀

The 39 is the lowest hexadecimal number among the given numbers.

Because 39 hex is equal to 57 decimal.

39 = (39)₁₆ = (3 × 16¹) + (9 × 16⁰) = (57)₁₀

Zina [86]
We can define a word as a group of characters without a space between them. To find the words of the input string , w can use split(delimiter) which returns a list of strings which had the defined delimiter between them in the input string.

def countWords(string):
words = string.split(" ")
count = len(words)
return count

Here we set the delimiter as the space character, and returned the length of the words list. I split each step into its own line for readability, however the function could be one line:

return len(string.split())

Here, no delimiter is specified. If one isn't given, it will default to split at any whitespace, including space.

When you hear music, read a printout, or view a video, you are using a computer's
Alik [6]

Answer:

Output device.

Explanation:

An output device can be defined as a hardware device that typically receives processed data from the central processing unit (CPU) and converts these data into information that can be used by the end user of a computer system.

All of the output device of a computer are known as peripheral devices and they provide data (informations) to the end users in various formats such as video, audio, texts, images etc.

Since output devices are peripheral devices, they can be connected to the computer system wirelessly or through a wired-connection (cable).

Some examples of output devices are monitor, speakers, printer, projector etc.

Hence, when you hear music, read a printout, or view a video, you are using a computer's output device.

A leading pharmaceutical company is launching a major transformation of its entire Cloud operations in order to more quickly and
klasskru [66]

This is a great move for the Pharmaceutical company for a number of reasons.

  • The first and perhaps most important advantage is to the company is that costs relating to Information and Technology (IT) Infrastructure will be reduced to the barest minimum. As a start-up, it is important to keep costs as low as possible. Costs are kept low because the organization will not need to pay the added energy and personnel-related costs of maintaining an elaborate IT infrastructure.

  • The advantage of scalability. Scalability in this sense simply means the ability to take on additional workload or adjust to market demand. As the company grows and attracts more clients, it would need to expand beyond the capacity that it had at the onset. Opting for Cloud as a Service (CaaS) gives them this advantage.

  • Another way CaaS can help the client is that they enjoy the advantage of Business Continuity. Business Continuity is the ability to remain in business regardless of disruptions to the business itself at one location. This is because CaaS providers are structured in such a way that they are able to keep their subscribers in operation regardless of any disasters.

Other advantages to this client are:

  1. Ease and access of automatic updates to the system;
  2. Ease of collaboration between internal and external users of the same system.

A perfect binary tree is a complete binary tree with all levels fully filled. Add a method in the BST class to return true if th
algol [13]

Answer:

class BST {

static class Node

{

int val;

Node left, right;

}

static boolean checkPerfectBT(Node node, int h, int d)

{

if (node == null)

return true;

 

if (node.left == null && node.right == null)

{

if(h==d+1)

return true;

else

return false;

}

 

if (node.left == null || node.right== null)

return false;

 

return checkPerfectBT(node.left, h, d+1) && checkPerfectBT(node.right, h, d+1);

}

static int height(Node node)

{

int dep = 0;

while (node != null)

{

node = node.right;

dep=dep+1;

}

return dep;

}

static boolean isPerfectBT(Node node)

{

int h = height(node);

return checkPerfectBT(node, h, 0);

}

 

static Node addNode(int x)

{

Node node = new Node();

node.val= x;

node.right = null;

node.left = null;

return node;

}

public static void main(String args[])

{

int i,j,k;

Node node= null;

node = addNode(34);

node.left = addNode(2);

node.right = addNode(322);

 

node.left.left = addNode(21);

node.left.right = addNode(23);

node.right.left = addNode(37);

node.right.right = addNode(54);

 

if (isPerfectBT(node) == true)

System.out.println("This is a Perfect Binary tree");

else

System.out.println("This is Not a perfect Binary Tree");

}

}

Explanation:

  • Calculate the depth of BST by using a while loop until it reaches a null value.
  • In the addNode method, make an object of Node class.
  • In the main method, pass the values to addNode method.
  • Finally display the relevant message to show if it's Perfect or not.

You try to enter your name into a cell that accepts a numeric value. What error would you receive? A. #NAME B. #VALUE C. #REF D.
UNO [17]

Answer:

<h2>Option B: #VALUE</h2>

is the correct answer.

Explanation:

<h3>Reasons of #VALUE error:</h3>
  • When cells are not given the expected type of value.
  • If cells are left blank unnoticeable or for giving a null value.
  • For entering dates and other numerical data in text form.
<h3>Correcting and fixing #VALUE error:</h3>

This type of error can only be fixed by finding the cell in which there is wrong data entered and correct it.

Fixing the #VALUE error is tricky as some functions automatically ignore the data that is invalid.

<h3>EXAMPLE:</h3>
  • Suppose a cell contains the value as cost of the object and in order to make it 0, NA is inserted into the cell.
  • While making total of all the costs, that particular cell might cause #VALUE error.
  • Following image attach will help you clear the concept.

I hope it will help you!
