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],
[1, 3, 4, 2], [3, 1, 4, 2], [3, 4, 1, 2], [3, 4, 2, 1],
[1, 2, 4, 3], [2, 1, 4, 3], [2, 4, 1, 3], [2, 4, 3, 1],
[1, 4, 2, 3], [4, 1, 2, 3], [4, 2, 1, 3], [4, 2, 3, 1],
[1, 4, 3, 2], [4, 1, 3, 2], [4, 3, 1, 2], [4, 3, 2, 1]]
Answer:
def permutations(myList: list)-> list:
if len(myList) <= 1:
return [myList]
perm = []
for i in range(len(myList)):
item = myList[i]
seglists = myList[:i] + myList[i+1:]
for num in permutations(seglists):
perm.append([item] + num)
return perm
data = [1,2,3]
result = permutations(data)
print(result)
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.
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.
Write a print statement that uses an f-string to output $5,242.83
Answer:
print("${:,.2f}".format(5242.83))
Explanation:
Given
$5,242.83
Required
Use an f string to output the above
The syntax of an f-string to format a number in that regard is: "${:,.2f}".format(number)
$ means that a dollar sign be printed before the required number
., means that the number be separated with commas
2f means that the number be presented in 2 decimal places
So:
"${:,.2f}".format(number) becomes
"${:,.2f}".format(5242.83)
In a print statement, the full instruction is:
print("${:,.2f}".format(5242.83))
In Linux, users are internally represented using a unique number called user ID or uid.
a. True
b. False
Answer:
a. True
Explanation:
An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.
This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.
Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.
In Linux, users are internally represented using a unique number called user ID or UID. Thus, this unique number serves as an internal identifier in the Linux Kernel and as such determines what system resources may be accessible to each user. Oftentimes, these unique numbers are not put into use but rather a name is linked with the number and are used instead.
Also, users can be organized logically into a group and are represented uniquely with a group ID or GID, which serves as a global identifier for the users.

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.
