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.

Explanation:
A data science experiment you are conducting has retrieved two historical observations for the price of Bitcoin(BTC) on December 2, 2017 of 11234 and 12475. Create a Python script that stores these two historicalobservations in a list variable namedbtcdec1.
Answer:
In Python:
btcdec1 = []
btcdec1 = [11234, 12475]
print(btcdec1)
Explanation:
First, create an empty list named btcdec1
btcdec1 = []
Next, insert the two data (11234 and 12475) into the list
btcdec1 = [11234, 12475]
Lastly, print the list
print(btcdec1)
Here is the problem specification: An Internet service provider has three different subscription packages for its customers: Package A: For $9.95 per month 10 hours of access are provided. Additional hours are $2.00 per hour. Package B: For $14.95 per month 20 hours of access are provided. Additional hours are $1.00 per hour. Package C: For $19.95 per month unlimited access is provided. Write a program that calculates a customer's monthly bill. It should ask which package the customer has purchased and how many hours were used. It should then display the total amount due. Input Validation: Be sure the user only selects package A, B or C. Also, the number of hours used in a month cannot exceed 744. Use switch.
Answer:
In C++:
#include <iostream>
using namespace std;
int main(){
int hour; char pkg; float bill = 0;
cout<<"Package: "; cin>>pkg;
cout<<"Hour: "; cin>>hour;
if(hour<=744 && hour >=0){
switch (pkg) {
case 'A':
bill = hour * 9.95;
if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}
break;
case 'B':
bill = hour * 14.5;
if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}
break;
case 'C':
bill = 19.95;
break;
default:
cout << "Package must be A, B or C";}
cout<<"Total Bills: $"<<bill; }
else{ cout<<"Hour must be 0 - 744"; }
return 0;
}
Explanation:
This declares all variables: int hour; char pkg; float bill=0;
This prompts the user for package type: cout<<"Package: "; cin>>pkg;
This prompts the user for number of hours: cout<<"Hour: "; cin>>hour;
This checks if hour is between 0 and 744 (inclusive)
if(hour<=744 && hour >=0){
If true, the following is executed
A switch statement to check valid input for package
switch (pkg) {
For 'A' package
case 'A':
Calculate the bill
bill = hour * 9.95;
if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}
End of A package: break;
For 'B' package
case 'B':
Calculate the bill
bill = hour * 14.5;
if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}
End of B package: break;
For C package
case 'C':
Calculate bill: bill = 19.95;
End of C package: break;
If package is not A, or B or C
default:
Prompt the user for valid package cout << "Package must be A, B or C";}
Print total bills: cout<<"Total Bills: $"<<bill; }
If hour is not 0 to 744: else{ cout<<"Hour must be 0 - 744"; }

The objective of this task is to use Scapy to estimate the distance, in terms of number of routers, between your VM and a selected destination. This is basically what is implemented by the traceroute tool. In this task, we will write our own tool. The idea is quite straightforward: just send a packet (any type) to the destination, with its Time-To-Live (TTL) field set to 1 first. This packet will be dropped by the first router, which will send us an ICMP error message, telling us that the time-to-live has exceeded. That is how we
This project is based on SEED labs by Wenliang Du, Syracuse University.
get the IP address of the first router. We then increase our TTL field to 2, send out another packet, and get the IP address of the second router. We will repeat this procedure until our packet finally reach the destination. It should be noted that this experiment only gets an estimated result, because in theory, not all these packets take the same route (but in practice, they may within a short period of time). The code in the following shows one round in the procedure
a = IP()
a.dst '1.2.3.4
a.ttl = 3
b = ICMP()
send (a/b)
If you are an experienced Python programmer, you can write your tool to perform the entire procedure automatically. If you are new to Python programming, you can do it by manually changing the TTL field in each round, and record the IP address based on your observation from Wireshark. Either way is acceptable, as long as you get the result
Task: Sniffing and-then Spoofing
In this task, you will combine the sniffing and spoofing techniques to implement the following sniff- and-then-spoof program. You need two VMs on the same LAN. From VM A, you ping an IP X. This will generate an ICMP echo request packet. If X is alive, the ping program will receive an echo reply, and print out the response. Your sniff-and-then-spoof program runs on VM B, which monitors the LAN through packet sniffing. Whenever it sees an ICMP echo request, regardless of what the target IP address is, your program should immediately send out an echo reply using the packet spoofing technique. Therefore, regard-less of whether machine X is alive or not, the ping program will always receive a reply, indicating that X is alive. You need to use Scapy to do this task. In your report, you need to provide evidence to demonstrate that your technique works.

Define a class named Money that stores a monetary amount. The class should have two private integer variables, one to store the number of dollars and another to store the number of cents. Add accessor and mutator functions to read and set both member variables. Add another function that returns the monetary amount as a double. Write a program that tests all of your functions with at least two different Money objects.
Answer:
#include<iostream>
using namespace std;
class Money{
private:
int dollars;
int cents;
public:
Money(int d=0, int c=0){
setDollar(d);
setCent(c);
}
void setDollar(int d){
dollars = d;
}
void setCent(int c){
cents = c
}
int getDollar() {
return dollars;
}
int getCent() {
return cents;
}
double getMoney(){
return (dollars + (cents/100));
}
};
// testing the program.
int main(){
Money Acc1(3,50);
cout << M.getMoney() << endl;
Money Acc2;
Acc2.setDollars(20);
Acc2.setCents(30);
cout <<"$" << Acc2.getDollars() << "." << Acc2.getCents() << endl;
return 0;
}
Explanation:
The C++ source code defines the Money class and its methods, the class is used in the main function as a test to create the instances of the money class Acc1 and Acc2.
The object Acc2 is mutated and displayed with the "setDollar and setCent" and "getDollar and getCent" methods respectively.

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.

You are a new salesperson at a large software manufacturing firm. It is three weeks from the end of the sales quarter and you and your sales manager are sitting pretty—you have both already met your sales quota for the quarter. In addition, you just closed another deal with a new customer for $100,000 of software and customer service. This order would put you way over your sales quota for the current quarter. Your manager suggests that you hold this new order so it gets recorded against next quarter. She explains that because sales during the next three months tend to slow down, salespeople frequently miss their quotas and associated sales bonuses for that quarter. Holding this large order to next quarter would help you get an excellent start and almost guarantee that you meet your quota. What would you do?
