Use EBNF notation to describe the syntax of the following language constructs.
A. A Java return statement, which could be either a return keyword followed by a semicolon, or a return keyword followed an expression then followed by a semicolon. Assume the grammar for expression has been defined as expr-> e
B. A Python return statement, either a return keyword, or return one or more expressions separated by comma.
C. Based on your syntax definition in (b), is return x+y; a valid Python return statement?
Answer:
Following are the description to the given points:
Explanation:
To resolve basic design restrictions, EBNF has also been developed.This principle was its lack of support can identify repeatings easily. It implies that popular BNF models, like the description of a sequence of replicable elements, are complicated and rely on contra intuitive logical math.
To set a list of words divided by commas (e.g. john, coffee, logic) for instance, we would like to say something like "a list is a word accompanied by a few commas or terms." Through EBNF, they may say so. However, there have been no "many" alternatives in the standard BNF format. So, to describe something such as "a list is a term or a number accompanied by a pair with notation and script," you have to say the same thing. Which functions, although it is difficult, as it specifies a variety of lists instead of a specific list.
Essentially, "john, coffee, logic is John's list, accompanied by coffees or, and logic" would be the earlier link. That's why in Option (a):
The return statement in Java is:
return ('”‘ (~[“] | ” [”e‘])*);
In option (c), it is the valid statement.

There Will Come Soft Rains is a warning story about nuclear war and how, in the end, technology won't keep us safe. In response to the atomic bombings of Hiroshima and Nagasaki, Bradbury penned the tale.
What author’s worried tone indicate about rain?Ray Bradbury wrote the classic science fiction short tale “There Will Come Soft Rains” in 1950. The narrative is narrated in a detached, emotionless tone, as though the events that are taking place are a normal part of everyday life.
The story's meaning can be found in the story's complete lack of human beings, not even corpses.
Soft rain rays will appear in the short story. Bradbury creates a disorganized, somewhat post-apocalyptic atmosphere. To better understand the zeitgeist of the world, he employs a variety of literary techniques.
Therefore, It's the worried tone author’s.

You are asked to write a program that prompts the user for the size of two integer arrays, user input for the size must not exceed 50, you must validate this. We will use these arrays to represent our sets. These arrays will be randomly populated in the range that is 1 through double the size of the array. So if the array is of size 20, you will randomly populate it with values in the range 1-40 inclusive.
Answer:
In Java:
import java.util.*;
public class MyClass{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
System.out.print("Length of array 1: ");
int lent1 = input.nextInt();
while(lent1 <= 0 || lent1 > 50){
System.out.print("Length of array 1: ");
lent1 = input.nextInt();
}
int[] array1 = new int[lent1];
System.out.print("Length of array 2: ");
int lent2 = input.nextInt();
while(lent2 <= 0 || lent2 > 50){
System.out.print("Length of array 2: ");
lent2 = input.nextInt();
}
int[] array2 = new int[lent2];
for(int i =0;i<lent1;i++){
array1[i] = (int)(Math.random() * (lent1*2) + 1);
}
for(int i =0;i<lent2;i++){
array2[i] = (int)(Math.random() * (lent2*2) + 1);
}
System.out.print("Array 1: ");
for(int i =0;i<lent1;i++){
System.out.print(array1[i]+" ");
}
System.out.println("Array 2: ");
for(int i =0;i<lent2;i++){
System.out.print(array2[i]+" ");
}
}
}
Explanation:
This prompts the user for length of the first array
System.out.print("Length of array 1: ");
This declares and gets input for the length of the first array
int lent1 = input.nextInt();
This validates the length of first array
while(lent1 <= 0 || lent1 > 50){
System.out.print("Length of array 1: ");
lent1 = input.nextInt(); }
This declares the first array
int[] array1 = new int[lent1];
This prompts the user for length of the second array
System.out.print("Length of array 2: ");
This declares and gets input for the length of the second array
int lent2 = input.nextInt();
This validates the length of the second array
while(lent2 <= 0 || lent2 > 50){
System.out.print("Length of array 2: ");
lent2 = input.nextInt(); }
This declares the second array
int[] array2 = new int[lent2];
The following generates random integers between 1 and lent1*2 to array 1
for(int i =0;i<lent1;i++){
array1[i] = (int)(Math.random() * (lent1*2) + 1); }
The following generates random integers between 1 and lent2*2 to array 2
for(int i =0;i<lent2;i++){
array2[i] = (int)(Math.random() * (lent2*2) + 1); }
This prints the header Array 1
System.out.print("Array 1: ");
The following iteration prints the content of the first array
for(int i =0;i<lent1;i++){
System.out.print(array1[i]+" ");
}
This prints the header Array 2
System.out.println("Array 2: ");
The following iteration prints the content of the second array
for(int i =0;i<lent2;i++){
System.out.print(array2[i]+" ");
}

Q3: Create a class called Employee that includes three instance variables—a first name (typeString), a last name (type String) and a monthly salary (double). Provide a constructor that initializesthe three instance variables. Provide a set and a get method for each instance variable. If the monthly salary is not positive, do not set its value. {Do not write a full program, only a class}
Answer:
Follows are the code to the given question:
public class Employee //defining a class Employee
{
String first_name,last_name;
Double monthly_salary;
Employee(String first_name,String last_name,Double monthly_salary)
{
this first_name=f_name// initialize value in first_name
this last_name = l_name; // initialize value in the last_name
this monthly_salary = m_salary; // initialize value in the monthly_salary
if (monthly_salary < 0.0)//use if to check monthly_salary is positive
monthly_salary = 0.0;//set value 0
}
void setfirst_name (String f_name)//defining set method to store first_name
{
first_name = f_name; //holding the value of first_name
}
public String getfirst_name ()//defining get method to return first_name
{
return first_name;//return first_name
}
public void setlast_name (String l_name)//defining set method to store last_name
{
last_name = l_name; // holding the value of the last_name
}
public String getlast_name ()//defining get method to return last_name
{
return last_name;//return last_name
}
public void setmonthly_salary(double m_salary)//defining set method to store monthly_salary
{
monthly_salary = m_salary; // holding the value of the monthly_salary
}
public double getmonthly_salary ()//defining get method to return monthly_salary
{
return monthly_salary;//return monthly_salary
}
}
Explanation:
In this code, a class "Employee" is declared that defines two string variables "first_name,last_name", and one double variable "monthly_salary". In the next step, a parameterized constructor is defined that stores the value into the variable, and use if block to check "monthly_salary" is a positive. It also uses the getter and setter method to hold and return its value.

Hello! So I have been practising some coding, however, there seems to be an error in my code. I have been trying to figure out what is wrong, however, I just can't seem to find it. There is no syntax error but, there seems to be a problem with my input. I am currently using repl.it and I am making a calculator. I would input something like "multiply" however, the calculator would only square. I have tried changing the variables but it just keeps coming back to the first "if" statement. I would appreciate some help.
Answer:
You OR expressions are wrong.
Explanation:
Rather than writing:
if method == "Square" or "square":
You should write:
if method == "Square" or method == "square":
The expression should evaluate to something that is true or false.
In the above case, the expression is method == "Square" or method == "square" which can are actually two sub-expressions with an or in between them:
subexpr1 or subexpr2
each of the sub-expressions should evaluate to true or false.
method == "Square" is one of those sub-expressions.
That is how an expression is broken down by the compiler.
TIP: If you would add method = method.lower() right after the input, you could simplify all the if statements by removing the uppercase variants.

Answer:
Follows are the code to the given question:
#include <stdio.h>//header file
int main()//main method
{
int count=0;//defining an integer variable
for(count=0;count<3;count++)//use for loop to count values
{
printf("%d\n",count);//print count values
}
return 0;
}
Output:
0
1
2
Explanation:
In this code, it declares the integer variable "count" which has a value of "0" and in the next step declares a loop, using the count variable to regulate count values, which is less than 3, and increases the count value, and prints its values. This variable is the count value.
The count variable holds a value of 0, and use a for loop that checks its value is less than 3, and print its value, that's why it will print the value that is 0,1, and 2.

What is an algorithm?The definition of algorithms in computer science. An algorithm is a list of instructions used in computer science to solve problems or carry out activities based on knowledge of potential solutions.
Think of a "black box," or a container where nobody can see what is occurring within. The box accepts our input and produces the output we require, but the process by which input is transformed into the intended output—and which we may need to understand—is an ALGORITHM.
Therefore, the correct option is B. myllum - RANDOM(1, 18)REPEAT UNTIL (byllum > 8){DISPLAY(myNum)myllum - RANDOM(1,18)}DISPLAY("Done").

Write code to take two words from the user. The program should convert these to lower case, then compare them: printing a positive number if string1 appears after string2 alphabetically, a negative number if string1 appears before string2 alphabetically and zero if the two strings are identical. Make sure your program does not produce any additional numerical output other than this number or it may not be graded correctly.
Answer:
Use compareTo.
Explanation:
import java.util.Scanner;
public class U2_L3_Activity_Three{
public static void main(String[] args){
Scanner scan = new Scanner(System.in);
System.out.println("Enter first word: ");
String word1 = scan.nextLine();
System.out.println("Enter second word: ");
String word2 = scan.nextLine();
//I had to make the string all lowercase or all uppercase for when I did this
word1 = word1.toLowerCase();
word2 = word2.toLowerCase();
System.out.println("Result: " + word1.compareTo(word2));
}
}
Following are the program to converting string value into lowercase and compare with an input string value.
Program Explanation:
Import package.Defining a class Dat.Inside the class defining the main method, and in the method, two string variable "string1, string2" is declared.After input, the value a "toLowerCase" method is used that converts string value into lower case. After converting value into the lower case a "compareTo" method is used that compares value and prints its value.Program:
import java.util.*;//import package for input
public class Dat //defining a Dat
{
public static void main(String[] ax)//main method
{
String string1 ,string2; //defining String variable
Scanner sc = new Scanner(System.in);//creating Scanner class object to input value
System.out.println("Enter values: ");//print message
string1= sc.next();//input value
string2= sc.next();//input value
string1= string1.toLowerCase();//convert string value into LowerCase
string2 = string2.toLowerCase();//convert string value into LowerCase

Write your own printArray() function found in Processing for the Arduino. For simplicity, you can limit printArray() to integer arrays and you will also pass the size of the array to your function. For example, given the following code:
int terps[5] = {7, 9, 12, 1, 46};
void printArray(int arrayToPrint[], int arraySize) { // YOUR CODE HERE }
void setup()
{ // put your setup code here, to run once:
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
printArray(terps,sizeof(terps)/sizeof(int)); delay(1000);
}
You should repeatedly see the following in the serial monitor:
[0]: 7
[1]: 9
[2]: 12
[3]: 1
[4]: 46
Answer:
Follows are the method definition to this question:
void printArray(int arrayToPrint[], int arraySize) //defining a method printArray that accepts two array in its parameters
{
for (int j = 0; j < arraySize; j++)//defining for loop print Serial numbers
{
Serial.print("[");//use print method to print square bracket
Serial.print(j);//use print method to print Serial numbers
Serial.print("]: ");//use print method to print square bracket
Serial.println(arrayToPrint[j]);//printing array value
}
}
Explanation:
In the above code, a method "printArray" is declared that holds two arrays "arrayToPrint and arraySize" as a parameter, and inside the method is used for loop to print the values.

Therefore, memory is of the utmost importance and all programming code needs to be optimized to use the least amount of memory possible. What modifications could be made to reduce the memory requirements without changing the overall functionality of the code?
Answer:
Move Line 10 to after line 12
Explanation:
Required: Modify the program
From the procedure above, the procedure prints the sum at each loop. Unless it is really necessary, or it is needed to test the program, it is not a good practice.
To optimize the program, simply remove the line at displays the sum (i.e. line 10) and place it at the end of the loop.
So, the end of the procedure looks like:
Line 10: i <-- i 2
Line 11: }
Line 12: DISPLAY ( sum )

Implement the function permutations() that takes a list lst as input and returns a list of all permutations of lst (so the returned value is a list of lists). Do this recursively as follows: If the input list lst is of size 1 or 0, just return a list containing list lst. Otherwise, make a recursive call on the sublist l[1:] to obtain the list of all permutations of all elements of lst except the first element l[0]. Then, for each such permutation (i.e., list) perm, generate permutations of lst by inserting lst[0] into all possible positions of perm.
>>> permutations([1, 2])
[[1, 2], [2, 1]]
>>> permutations([1, 2, 3])
[[1, 2, 3], [2, 1, 3], [2, 3, 1], [1, 3, 2], [3, 1, 2], [3, 2, 1]]
>>> permutations([1, 2, 3, 4])
[[1, 2, 3, 4], [2, 1, 3, 4], [2, 3, 1, 4], [2, 3, 4, 1],
[1, 3, 2, 4], [3, 1, 2, 4], [3, 2, 1, 4], [3, 2, 4, 1],

Explanation:
The program defines a python function that returns the list of permutations. The program checks if the length of the input list is less than or equal to one. The function declaration identifies the input and output as lists.
The for loop iterate through the list and the permutations are saved in an empty list in the next loop statement. At the end of the program, the list of lists is returned.
