Answer:

modulation

Explanation:

Modulation is the procedure of encoding data into electrical signals for transmission through a media. For transmission, binary information, denoted by a sequence of ones and zeros, should be translated to analog or digital electrical signals. The method converts data into electrical signals suited for transmission is known as modulation. Digital modulation is the transmission of binary signals zeroes and ones.

Define a function below called nested_list_string. The function should take a single argument, a list of lists of numbers. Compl

DerKrebs [107]

Answer:

The solution code is written in Python:

def nested_list_string(list2D):
output = ""
for i in range(0, len(list2D)):
for j in range(0, len(list2D[i])):
output += str(list2D[i][j]) + " "
return output

Explanation:

Let's create a function and name it as nested_list_string() with one input parameter, list2D (Line 1).

Since our expected final output is a string of number and therefore we define a variable, output, to hold the string (Line 2).

Next use two for loops to traverse every number in the list and convert each of the number to string using str() method. Join each of individual string number to the output (Line 3-5).

At the end, we return the output (Line 7)

g Write a program that asks for the weight of a package and the distance it is to be shipped. This information should be passed

DIA [1.3K]

Answer:

I am writing a C++ program:

#include <iostream> //to use input output functions

#include<iomanip> // to format the output

using namespace std; // to identify objects like cin cout

void calculateCharge(double weight, double distance); // function prototype

int main(){ //start of main() function body

double w = 0.0, t = 0.0; // w variable is for weight and t is for total

unsigned int d = 0; // d variable is to hold the value of distance

calculateCharge(w, d); } //calls calculateCharge method by passing weight and distance values to this method

void calculateCharge(double weight, double distance){ //method that takes weight and distance as parameters and compute the shipping charge

double charge = 0.0; //to store the value of shipping charges

do { // do while loop to handle multiple packages until a weight of 0 is entered

cout << "Enter weight: " << endl; //prompts user to enter weight

cin >> weight; //reads the input weight value

if (weight == 0){ // if the value of weight is equal to 0

break; } // the loop breaks if value of weight is 0

cout << "Enter distance: " << endl; // if value of weight is not zero then the program precedes by prompting user to enter the value of distance

cin >> distance; //reads the input distance value

cout << fixed << setprecision(2) << endl; //set the precision to 2 means the sets the number of digits of an output to 2 decimal places

if(weight <= 2) //if the value of weight is less than or equals to 2

charge = (distance/500) * 3.10; //compute the charge by this formula

else if(weight > 2 && weight <= 6) //if weight is over 2 kg but not more than 6 kg

charge = (distance/500) * 4.20; //charge is computed by multiplying value of distance to that of weight and if distance is greater than 500 then it is divided by 500 first

else if(weight > 6 && weight <= 10) // if weight is over 6 kg but not more than 10 kg

charge = (distance/500) * 5.30; //compute shipping charges by this formula

else //if weight is over 10 kg

charge = (distance/500) * 6.40; // compute shipping charge by multiplying value of distance to that of 6.40 weight value and if distance is greater than 500 then distance is divided by 500 first

cout << "Shipping charges: $" << charge << "\n"; //display the computed shipping charge

} while (weight != 0); //the loop continues to execute until weight 0 is entered

}

Explanation:

The program is explained in the comments mentioned above. The program has a main() function that declares variable for weight, distance and total and then calls calculateCharge() method passing weight and dsitance in order to compute and return the shipping charge.

In calculateCharge() the user is prompted to enter the values for weight and distance. Then the based on the value of weight , the shipping charge is computed. Shipping charge is computed by multiplying the weight with distance. The distance is assumed to be 500 but if the distance entered by user exceeds 500 then the distance value is divided by 500 and then multiplied by the specified weight (according to if or else if conditions) in order to compute shipping charge. The program has a do while loop that keeps taking input from user until the user enters 0 as the value of weight.

The screenshot of the program and its output is attached.

Write a method called compress that takes a string as input, compresses it using rle, and returns the compressed string. case ma

MaRussiya [10]

public static String compress (String original) { StringBuilder compressed = new StringBuilder(); char letter = 0; int count = 1; for (int i = 0; i < original.length(); i++) { if (letter == original.charAt(i)) { count = count + 1; } else { compressed = count !=1 ? compressed.append(count) : compressed; compressed.append(letter); letter = original.charAt(i); count = 1; } } compressed = count !=1 ? compressed.append(count) : compressed; compressed.append(letter); return compressed.toString(); }

Which of the following statements is true?

jeka57 [31]

Answer: Constructors can specify parameters but not return types.

Explanation:

public class Student {

int roll_no;

public Student(int a) {

roll_no = a;

}

public static void main(String[] args) {

Student abs = new Student(10);

System.out.println(abc.roll_no);

}

In the above code we have illustrated the working of constructors. We have a class with the name Student. then a constructor is created of the class called as the class constructor. In the main we create an object of the class and with this object we invoke the constructor and also pass a parameter. Here in the code we are passing the roll no of the student.

So we can say that constructor is called during the runtime when the object created invokes the constructor so a constructor can have many arguments but it does not have a return type.
