Write a removeDuplicates() method for the LinkedList class we saw in lecture. The method will remove all duplicate elements from the LinkedList by removing the second and subsequent elements. If there is only one copy of an element, it is not removed. The list size should shrink accordingly based on the number of duplicates removed.

Answer:

removeDuplicates() function:-

//removeDuplicates() function removes duplicate elements form linked list.

   void removeDuplicates() {

     

       //declare 3 ListNode pointers ptr1,ptr2 and duplicate.

       //initially, all points to null.

       ListNode ptr1 = null, ptr2 = null, duplicate = null;

       

       //make ptr1 equals to head.

       ptr1 = head;

        //run while loop till ptr1 points to second last node.

       //pick elements one by one..

       while (ptr1 != null && ptr1.next != null)

       {

               // make ptr2 equals to ptr1.

               //or make ptr2 points to same node as ptr1.

           ptr2 = ptr1;

           //run second while loop to compare all elements with above selected element(ptr1->val).

           while (ptr2.next != null)

           {

              //if element pointed by ptr1 is same as element pointed by ptr2.next.

               //Then, we have found duplicate element.

               //Now , we have to remove this duplicate element.

               if (ptr1.val == ptr2.next.val)

               {

                  //make duplicate pointer points to node where ptr2.next points(duplicate node).

                       duplicate = ptr2.next;

                       //change links to remove duplicate node from linked list.

                       //make ptr2.next points to duplicate.next.

                   ptr2.next = duplicate.next;

               }

               

             //if element pointed by ptr1 is different from element pointed by ptr2.next.

               //then it is not duplicate element.

               //So, move ptr2 = ptr2.next.

Which network would the patrol services of a city's police department most likely use?

A. LAN
в.PAN
C.CAN
D.MAN

Answers

Answer:

D. MAN

Explanation:

A local area network (LAN) refers to a group of personal computers (PCs) or terminals that are located within the same general area and connected by a common network cable (communication circuit), so that they can exchange information from one node of the network to another. A local area network (LAN) is typically used in small or limited areas such as a set of rooms, a single building, school, hospital, or a set of well-connected buildings. Some of the network devices or equipments used in a local area network (LAN) includes an access point, personal computers, a switch, a router, printer, etc.

On the other hand, a metropolitan area network (MAN) is formed by an aggregation of multiple local area network (LAN) that are interconnected using backbone provided by an internet service provider (ISP). A metropolitan area network (MAN) spans for about 5 kilometers to 50 kilometers in size.

Basically, a metropolitan area network (MAN) spans across a geographic area such as a city and it's larger than a local area network (LAN) but significantly smaller than a wide area network (WAN).

In conclusion, the network type that the patrol services of a city's police department would most likely use is a metropolitan area network (MAN).

Answers

Answer:

Following are the code to the given question:

user_num = int(input())#defining a variable user_num that takes input from user-end

x = int(input())#defining a variable x that takes input from user-end

for j in range(3):#defining for loop that divides the value three times

   user_num = user_num // x#dividing the value and store integer part

   print(user_num)#print value

Write a program that will read two floating point numbers (the first read into a variable called first and the second read into a variable called second) and then calls the function swap with the actual parameters first and second. The swap function having formal parameters number1 and number2 should swap the value of the two variables.
Sample Run:
Enter the first number
Then hit enter
80
Enter the second number
Then hit enter
70
You input the numbers as 80 and 70.
After swapping, the first number has the value of 70 which was the value of the
second number
The second number has the value of 80 which was the value of the first number

Answers

Answer:

The program in Python is as follows:

def swap(number1,number2):

   number1,number2 = number2,number1

   return number1, number2

   

first = int(input("First: "))

second = int(input("Second: "))

print("You input the numbers as ",first,"and",second)

first,second= swap(first,second)

print("After swapping\nFirst: ",first,"\nSecond:",second)

Explanation:

This defines the function

def swap(number1,number2):

This swaps the numbers

   number1,number2 = number2,number1

This returns the swapped numbers

   return number1, number2

The main begins here

This gets input for first    

first = int(input("First: "))

This gets input for second

second = int(input("Second: "))

Print the number before swapping

print("You input the numbers as ",first,"and",second)

This swaps the numbers

first,second= swap(first,second)

This prints the numbers after swapping

print("After swapping\nFirst: ",first,"\nSecond:",second)

Answers

Answer:

The output is:

1 2 3 4 5

Explanation:

Given

See attachment for code segment

Required

The output of rec2(5)

From the attached code segment, we have the following:

The base case: if (x==0){ return;}

The above implies that, the recursion ends when the value of x gets reduced to 0

The recursion:

rec2(x-1); ---- This continually reduces x by 1 and passes the value to the function

printf("%d ", x); This prints the passed value of x

Hence, the output of rec2(5) is: 1 2 3 4 5

Answer:

Option A (CRL) is the right answer.

Explanation:

Certificates with respective expiration date canceled mostly by CA generating or providing them, then it would no longer be tolerated, is considered as CRL.CRL verification could be more profitable for a platform that routinely manages several clients, all having pronouncements from a certain CA, because its CRL could be retrieved once per day.

Answer:

Explanation:

Using the main() and Instrument class which can be found online. We can create the following StringInstrument class that extends the Instrument class itself. The only seperate variables that the StringInstrument class posses' would be the number of Strings (numStrings) and the number of frets (numFrets). Due to technical difficulties I have added the code as a seperate text file below.

Which of the following will cause you to use more data than usual on your smartphone plan each month?

a. make a large number of outbound calls

b. sending large email files while connected to wifi

c. streaming movies from Netflix while not connected to Wi-Fi

d. make a large number of inbound calls

Answers

Outbound calls. You would most likely make more calls TO people rather than receive.

let's have a class named Distance having two private data members such as feet(integer), inches(float), one input function to input values to the data members, one Display function to show the distance. The distance 5 feet and 6.4 inches should be displayed as 5’- 6.4”. Then add the two objects of Distance class and then display the result (the + operator should be overloaded). You should also take care of inches if it's more than 12 then the inches should be decremented by 12 and feet to be incremented by 1.

A recursive method may call other methods, including calling itself. A recursive method has:
1. a base case -- a case that returns a value or exits from a method without performing a recursive call.
2. a recursive case -- calling the method again with a smaller case..
Study the recursive method given below.
For example, this call recursiveMethod (5); returns 15:
public static int recursiveMethod (int num) (
if (num == 0)
return 1;
else {
if (numX2!=0)
return num * recursiveMethod (num -1);
else
return recursiveMethod (num-1);
}
}
1 What is the base case?
2. What does the following statement check?
3. What does the method do?

Answers

Answer:

Hence the answer is given as follows,

Explanation:

Base Case:-  

If (num == 0) //This is the base case for the given recursive method  

return 1;  

If(num % 2!=0) checks whether num is odd.  

The above condition is true for all odd numbers and false for even numbers.  

if the remainder is not equal to zero when we divide the number with 2 then it is odd.  

The method:-  

The above recursive method calculates the product of odd numbers up to the given range(that is num)  

For num=5   => 15(5*3*1).  

For num=7   => 105(7*5*3*1).  

For num=10 => 945(9*7*5*3*1).

The answer is "Option c"

Explanation:

In PHP to remove all the session variables, we use the session_destroy() function. It doesn't take any argument is required and then all sessions variables could be destroyed by a single call. If a particular clinical variable is now to be destroyed, the unset() function can be applied to unset a session variable. Its session doesn't unset or unset the session cookie by either of the local variables associated with it.
