For an array of size N what is the range of valid indices (or subscripts)?

Answers

Answer 1

Answer:

The valid range is 0 to N - 1

Explanation:

Required

Valid range of an array of size N

The index of an array starts from 0, and it ends at 1 less than the size.

Take for instance:

An array of size 4 will have 0 to 3 as its indices

An array of size 10 will have 0 to 9 as its indices

Similarly,

An array of size N will have 0 to N - 1 as its indices

Reverse Word Order: Write a program that reverses the order of the words in a given sentence. This program requires reversing the order of the words wherein the first and last words are swapped, followed by swapping the second word with the second to last word, followed by swapping the third word and the third to last words, and so on. Your program will ask the user for an input string and print out the resultant string where the order of the words is reversed. Please see the hints section for more details on an example algorithm. Assume a maximum C-string size of 1000 characters. Make sure your code works for any input number, not just the test cases. Your code will be tested on other test cases not listed here. Do Not Use Predefined Functions from the cstring Library. Please properly comment your code before submission.For this part of the assignment, name your source file as Reverse Word Order_WSUID.cpp. For example, if your user ID is A999B999 name your file as Reverse Word Order_A999B999.cpp. Sample Test Cases: Test Case 1: Input: London bridge has been abducted Output: abducted been has bridge London Test Case 2: Input: Hello World Output: World Hello Test Case 3: Input: Hello World, how are you?

The program in C++ is as follows:

#include <bits/stdc++.h>

using namespace std;

int main(){

string sentence,word="";

getline (cin, sentence);

vector<string> for_reverse;

for (int i = 0; i < sentence.length(); i++){

 if (sentence[i] == ' ')  {

  for_reverse.push_back(word);

  word = "";  }

 else{    word += sentence[i];}  }

for_reverse.push_back(word);

sentence="";

for (int i = for_reverse.size() - 1; i > 0; i--){

 sentence+=for_reverse[i]+" ";}

sentence+=for_reverse[0];

cout<<sentence<<endl;

return 0;

}

Explanation:

This declares sentence and word as strings; word is then initialized to an empty string

string sentence,word="";

This gets input for sentence

getline (cin, sentence);

This creates a string vector to reverse the input sentence

vector<string> for_reverse;

This iterates through the sentence

for (int i = 0; i < sentence.length(); i++){

This pushes each word of the sentence to the vector when space is encountered

 if (sentence[i] == ' ')  {

  for_reverse.push_back(word);

Initialize word to empty string

  word = "";  }

If the encountered character is not a blank space, the character is added to the current word

 else{    word += sentence[i];}  }

This pushes the last word to the vector

for_reverse.push_back(word);  

This initializes sentence to an empty string

sentence="";

This iterates through the vector

for (int i = for_reverse.size() - 1; i > 0; i--){

This generates the reversed sentence

 sentence+=for_reverse[i]+" ";}

This adds the first word to the end of the sentence

sentence+=for_reverse[0];

Print the sentence

cout<<sentence<<endl;

Given the value x=false ,y=5 and z=1 what will be the value of F=(4%2)+2*Y +6/2 +(z&&x)?

Answers

Answer:

F = 13

Explanation:

Given:

x = false

y = 5

z = 1

F = (4%2)+2*Y +6/2 +(z&&x)

We solve this arithmetic using the order of precedence:

i. Solve the brackets first

=> (4 % 2)

This means 4 modulus 2. This is the result of the remainder when 4 is divided by 2. Since there is no remainder when 4 is divided by 2, then

4 % 2 = 0

=> (z && x)

This means (1 && false). This is the result of using the AND operator. Remember that && means AND operator. This will return false (or 0) if one or both operands are false. It will return true (or 1) if both operands are true.

In this case since the right operand is a false, the result will be 0. i.e

(z && x) = (1 && false) = 0

ii. Solve either the multiplication or division next whichever one comes first.

=> 2 * y

This means the product of 2 and y ( = 5). This will give;

2 * y = 2 * 5 = 10

=> 6 / 2

This means the quotient of 6 and 2. This will give;

6 / 2 = 3

iii. Now solve the addition by first substituting the values calculated earlier back into F.

F = (4%2)+2*Y +6/2 +(z&&x)

F = 0 + 10 + 3 + 0

F = 13

Therefore, the value of F is 13

Alex can refer to this desktop version of the website to create the mobile website design The desktop version of the website contains a long list of hyperlinks and this can obstruct the view of the main content when Viewed from a mobile device. Which of the following should Alex use to hide this long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list?
a. Navigator menus
b. Pulldown menus
c. Pop-up links
d. Header links

Answers

Answer: Pulldown menus

Explanation:

Pulldown menus refer to the graphical control element, that is identical to a list box, which enables user to be bake to select one value from a list.

They're regarded as the menu of options that will appear when an item is selected with a mouse. In this case, the item that the user selected will show at the top of the display screen, while the menu appears will show below it.

Therefore, Alex should use the pulldown menus to hide the long list of hypertext links so that it appears only in response to a tap of a major heading in the navigation list.

Write one or more constructors and the appropriate accessor and mutator functions for the class.
Next, write a class named ProductionWorker that is derived from the Employee class. The ProductionWorker class should have member variables to hold the following information:
Shift (an integer)
Hourly pay rate (a double)
The workday is divided into two shifts: day and night. The shift variable will hold an integer value representing the shift that the employee works. The day shift is shift 1 and the night shift is shift 2. Write one or more constructors and the appropriate accessor and mutator functions for the class.

Several families are planning a shared car trip on scenic drives in New Hampshire's White Mountains. To minimize the possibility of any quarrels, they want to assign individuals to cars so that no two members of a family are in the same car. Explain how to formulate this problem as a network flow problem.

Answers

Answer:

Following are the response to the given question:  

Explanation:

Build a spring, sink, vertices, and vertices for each car for a household. Every unit in the stream is a human. Attach the source from each vertical of a family with such a capacity line equivalent to the family size; this sets the number of members in each household. Attach every car vertices to the sink with the edge of the car's passenger belt; this assures the correct number of people for every vehicle. Connecting every vertex in your household to any vertex in your vehicle with a capacity 1 border guarantees that one family member joins a single car. The link between both the acceptable allocation of people to vehicles as well as the maximum flow inside the graph seems clear to notice.

Rearrange the program

There are no one way to solve questions like this. However, a simple guide is as follows:

All header files must be called first (i.e #include....)

Followed by the namespaces (std)

if the program uses constant, the constant must be declared and initialized.

e.g. const double PI = 3.14159;

Next, all variables and must be declared (e.g. double radius)

Next, all inputs must be taken before the values of the variables can be used (e.g. cin >> height;)

If the inputs used prompts, the prompt must be before the inputs.

Next, perform all computations then output the results

A company manufactures televisions. The average weight of the televisions is 5 pounds with a standard deviation of 0.1 pound. Assuming that the weights are normally distributed, what is the weight that represents the 75th percentile?​

Answers

Answer:

5.0674

Explanation:

Given that :

Mean, μ = 5 pounds

Standard deviation, σ = 0.1

Given that weight are normally distributed ;

From the Z table, the Zscore or value for 75th percentile weight is :

P(Z < z) = 0.75

z = 0.674

Using the relation :

Zscore = (x - μ) / σ

x = weight

0.674 = (x - 5) / 0.1

0.674 * 0.1 = x - 5

0.0674 = x - 5

0.0674 + 5 = x - 5 + 5

5.0674 = x

The weight which corresponds to the 75th percentile is 5.0674

Explanation:

Intangible advantages

Take faster decisionsCompetitive needMore information timelyNew, better or more information availability.

Lower productivity and the lack of 'think outside' employees and managers as well as greater sales include the intangible costs of such an operational environment. All these factors improve when employees spend less of their time in addressing current methods of operation and are concerned about whether they will have a job or an employer in six months or a year. The automation level envisaged in this new system should enhance the overall efficiency of management. The operative controls and design functions should be simplified by tight system integrations with accessible automated database sources. However, it is difficult to describe the exact form of these simplifications.

Tangible costs of the new system include costs of analysis, design and construction of the system, such as the recruitment of contractors or new employees, and the assignment of existing staff. Also consideration shall be given to hardware, software purchased and operating costs. Intangible costs include disturbances to the current activities caused by development and deployment and potential adverse effects on the morals of employees.

While the new system may feel good in the long term, short-term stress and other negative consequences will still be present. In the way that Reliable does virtually everything, the system is the focus of a major change. An organisation's monumental change has widespread negative effects on operations and employees.

The basic operations used to develop useful sets of data in relational database are Select, Project and Join.

The Select and Project are of important use in selecting columns or attributes which we want to display or include in a table.

The join function allows the merging of data tables to form a more complete and all round dataset useful for different purposes.

Hence, the basic operations are select, project, and join.

Pascaline, also called Arithmetic Machine.

(Ramanujan's Taxi) Srinivasa Ramanujan indian mathematician who became famous for his intuition for numbers. When the English mathemematician G.H. Hardy came ot visit him in the hospital one day, Hardy remarked that the number if his taxi was 1729, a rather dull number. To which Ramanujan replied, "No, Hardy! It is a very interesting number. It is the smallest number expressible as the sum of two cubes in two different ways." Verify this claim by writing a program Ramanujan.java that takes a command-line argument N and prints out all integers less than or equal to N that can be expressed as the sum of two cubes in two different ways. In other words, find distinct positive integers a, b, c, and d such that а3 + b3 = c3 - d3. Hint: Use four nested for loops, with these bounds on the loop variables: 0 < a < 3√N, a < b < 3√N - a3, a < c < 3√N and c < d < 3√N - C3; do not explicitly compute cube roots, and instead use x . x *x < y in place of х < Math.cbrt (y).

Here the code is given as follows,

Explanation:

Code:

public class Ramanujan {  

   public static void main(String[] args) {  

       // check cmd argument

       int n = Integer.parseInt(args[0]);  

       // checking a^3 + b^3 = c^3 + d^3  

       // outer loop

       for (int a = 1; (a*a*a) <= n; a++) {  

           int a3 = a*a*a;  

           // no solution is possible, since upcoming a values are more

           if (a3 > n)  

               break;  

           // avoid duplicate

           for (int b = a; (b * b * b) <= (n - a3); b++) {  

               int b3 = b*b*b;  

               if (a3 + b3 > n)

                   break;  

               // avoid duplicates

               for (int c = a + 1; (c*c*c) <= n; c++) {  

                   int c3 = c*c*c;  

                   if (c3 > a3 + b3)

                       break;  

                   // avoid duplicates

                   for (int d = c; (d * d * d) <= (n - c3); d++) {  

                       int d3 = d*d*d;  

                       if (c3 + d3 > a3 + b3)  

                           break;  

                       if (c3 + d3 == a3 + b3) {

                           System.out.print((a3+b3) + " = ");

                           System.out.print(a + "^3 + " + b + "^3 = ");  

                           System.out.print(c + "^3 + " + d + "^3");

Can Algorithms Be Used Again?

Answers

Answer:

Explanation:Algorithms are aimed at optimizing everything. They can save lives, make things easier and conquer chaos. Still, experts worry they can also put too much control in the hands of corporations and governments, perpetuate bias, create filter bubbles, cut choices, creativity and serendipity, and could result in greater unemploymen

Answer: The algorithm must have an infinite number of steps because there are an infinite number of integers greater than one. It will run forever trying to count to infinity. Every algorithm must reach some operation that tells it to stop.
