When developing an estimate, which of the following items is typically marked up with the highest percentage rate?

Determine the number of character comparisons made by the brute-force algorithm in searching for the pattern GANDHI in the text

leonid [27]

Answer:

Total number of character comparison = 43

Explanation:

Using the Brute force algorithm

The string of n characters is known as text, and the string of m characters is known as the pattern.

From the given information:

The text (n)=THERE_IS_MORE_TO_LIFE_THAN_INCREASING_ITS_SPEED

The pattern (m) = GANDHI

The total no of characters that we have in the text = 47

The total number of characters in pattern = 6

For a brute force algorithm;

Since; the first character of the pattern does not exist in the text, then the number of trials made can be attempted can be expressed as = n – m + 1

= 47 – 6 + 1

= 47 – 5

= 42

Thus; the algorithm will attempt the trial 42 times.

Now, for loop in the algorithm to run 42 times, the G in the pattern will have to align against the for T in the text, and in the last case, it will be aligned against the last space.

On each attempted trial, the algorithm will make one unsuccessful comparison.

However, at the trial at which the G in the pattern Is aligned with the G in the text, there will be two successful comparisons.

Hence, we can calculate the total number of character comparison as follows:

Total number of character comparison = $\mathbf{\bigg ( ( 42 - (no. \ of \ failed \ comparison) ) \times 1 + (1 \times ( Two \ successful \ comparisons) ) \bigg ) }$

Total number of character comparison = ( (( 42 – 1) × 1 ) + ( 1 × 2) )

Total number of character comparison = 41 + 2

Total number of character comparison = 43

Por qué no es tan común el uso de energías mas amigables con el medio ambiente en el país donde vives?

Effectus [21]

Answer:

Explanation:

English:

All forms of electricity generation have an environmental impact on our air, water, and land, but it varies. Of the total energy consumed in the United States, about 40% is used to generate electricity, making electricity use an important part of each person’s environmental footprint.

Producing and using electricity more efficiently reduces both the amount of fuel needed to generate electricity and the number of greenhouse gases and other air pollution emitted as a result. Electricity from renewable resources such as solar, geothermal, and wind generally does not contribute to climate change or local air pollution since no fuels are combusted.

The fuel mix for U.S. electricity generation

The chart below shows that most of the electricity in the United States is generated using fossil fuels such as coal and natural gas. A small but growing percentage is generated using renewable resources such as solar and wind.

Spanish:

Todas las formas de generación de electricidad tienen un impacto ambiental en nuestro aire, agua y tierra, pero varía. Del total de energía consumida en los Estados Unidos, alrededor del 40% se usa para generar electricidad, lo que hace que el uso de electricidad sea una parte importante de la huella ambiental de cada persona.

Producir y usar electricidad de manera más eficiente reduce tanto la cantidad de combustible necesario para generar electricidad como la cantidad de gases de efecto invernadero y otra contaminación del aire emitida como resultado. La electricidad de recursos renovables como la energía solar, geotérmica y eólica generalmente no contribuye al cambio climático ni a la contaminación del aire local, ya que no se queman combustibles.

Combustible para la generación de electricidad en EE. UU.

El cuadro a continuación muestra que la mayor parte de la electricidad en los Estados Unidos se genera utilizando combustibles fósiles como el carbón y el gas natural. Un porcentaje pequeño pero creciente se genera utilizando recursos renovables como la solar y la eólica.

Program 4 - Pick color Class Create a class that randomly pick a color from an array of colors: string colors[7]; Have the color

xxMikexx [17]

Answer:

#include<cstdlib>

#include<bits/stdc++.h>

#include<time.h>

using namespace std;

class Colors{

string colors[7];

public:

void setElement(int,string);

void printAllColors();

void printRandomColor();

};

void Colors::setElement(int index,string color){

colors[index] = color;

}

void Colors::printAllColors(){

cout << "Printing all the colors:\n";

for(int i=0;i<7;i++){

cout << colors[i] <<"\t";

}

void Colors::printRandomColor(){

srand (time(NULL));

int index = rand() % 7;

cout<< "\n\nThe random picked color:";

cout << colors[index] << endl;

}

int main(){

Colors color;

color.setElement(0,"red");

color.setElement(1,"orange");

color.setElement(2,"yellow");

color.setElement(3,"green");

color.setElement(4,"blue");

color.setElement(5,"indigo");

color.setElement(6,"violet");

color.printAllColors();

color.printRandomColor();

}

to get the random color we are using srand and rand function. we are using time as seed to srand() function,because every time the time is changed. And based on that we are using rand() function and doing mod with 7 with the random number to get the index between 0 to 6, as ut array size is 7(0 to 6).

In the setElement(int index,string color) method we are inserting the value of colors in the colors array based on index.

In the printAllColors() function we are printing all the colors in the array.

In the printRandomColor() er are printing any random color based on rand() function.

and in main() we are initializing the string array with colors and calling the functions.

Suppose you are provided with 2 strings to your program. Your task is to join the strings together so you get a single string wi

Mariulka [41]

Answer:

public class TestImport{

public static void main(String[] args) {

String string1 = args[1];

String string2 = args[2];

System.out.println(string1 +" " +string2);

}

Explanation:

The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);

When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
