### List Transformation in Programming#### Problem StatementA code segment is intended to transform the list `utensils` so that the last element of the list is moved to the beginning of the list.For example, if `utensils` initially contains `["fork", "spoon", "tongs", "spatula", "whisk"]`, it should contain `["whisk", "fork", "spoon", "tongs", "spatula"]` after executing the code segment.Which of the following code segments transforms the list as intended?#### Code Options**Option A:**```plaintextlen ← LENGTH(utensils)temp ← utensils[len]REMOVE(utensils, len)APPEND(utensils, temp)```**Option B:**```plaintextlen ← LENGTH(utensils)REMOVE(utensils, len)temp ← utensils[len]APPEND(utensils, temp)```**Option C:**```plaintextlen ← LENGTH(utensils)temp ← utensils[len]REMOVE(utensils, len)INSERT(utensils, 1, temp)```**Option D:**```plaintextlen ← LENGTH(utensils)REMOVE(utensils, len)temp ← utensils[len]INSERT(utensils, 1, temp)```#### Explanation and AnalysisThe goal is to take the last element of the list and move it to the beginning. To correctly achieve this:1. Determine the length of the list.2. Temporarily store the last element of the list.3. Remove the last element from the list.4. Insert the stored element at the beginning of the list.Let's analyze the options:**Option A Analysis:**1. `len ← LENGTH(utensils)` - This correctly assigns `len` the length of the list.2. `temp ← utensils[len]` - This attempts to access an element that is out of the index range (should be `utensils[len-1]`).3. `REMOVE(utensils, len)` - Removes an element that is out of the index range.4. `APPEND(utensils, temp)` - Appends the potentially invalid element to the end of the list.**Option B Analysis:**1. `len ← LENGTH(utensils)` - Correct.2. `

Largest Value. Create a program that uses a list to store input values, and outputs the largest value entered at its location in the list. The program shall accept input values until the user enters -1. And Next Movie Time. Create a program that shows the user when the next showing for a movie is. The program first reads the different showing times (only hours) in a 24-hour clock format (that is, 1PM is 13, 6PM is 18, etc.). The program then asks when a customer wants to go to the movies. The program replies with the time for the next showing. If the next showing matches the hour input by the customer, show the next showing after that. If the next showing is past the last one, the program shall output, “There are no more showings.”, Here is a sample execution: I am trying to use these programs as practice for practicing lists, strings and inputs. But am struggling a bit after laying down the foundation on each problem. I plan to put them into thonny to compare them with my own work.

List comprehension. Write a Python program called list_comprehension.py that contains remove_list = [1,5,7, 9]. Create a list that is initialized by a list comprehension that contains all numbers from 0-10, but none of the numbers on the remove_list. Do not use for loop. Print the contents of the list.
5 partition_list (head) This is a little like split_list() from the Short problem, except that, instead of splitting the list into two by cutting it into the middle, you will now build two lists to return, using alternate values. The first value in the input list should be returned at the head of the first new list; the second value should be the head of the second list. Keep on alternating from there, putting one new value on the first list, and one on the second. (But remember that the length of the input list might be odd.) Example Suppose you have the following input list: 10 - 13 -> -1 -> 1000 - 0 It should return the following two lists: 10 1 0 13 -> 1000
Help make a C++ program that:1. Queries the user for the name of a file of text.2. Opens the file, and maintains two lists: one list for words beginning with the letter"D" or "d", and a second list for words beginning with any other letter. Each listmust maintain words in alphabetical order.3. Each node in the list must contain the word and the number of times that the word appears.4. Display (a screen at a time) each of the lists showing the alphabetized list of words and thenumber of times that each appears. Please have the main function as the first function in the program. Please make the least amount of functions as possible. Like for the file input have the file error thing in the same function. And please add comments throughout the code.
Complete the reverse_list() function that returns a new string list containing all contents in the parameter but in reverse order. Ex: If the input list is: ['a', 'b', 'c'] then the returned list will be: ['c', 'b', 'a'] Note: Use a for loop. DO NOT use reverse() or reversed(). This is my code so far: def reverse_list(letters): for x in (letters): letters.sort(reverse=True) return lettersif __name__ == '__main__': ch = ['a', 'b', 'c'] print(reverse_list(ch)) # Should print ['c', 'b', 'a'] When submitting I get 4/10 and it says: Test input list ['a', 'b', 'c'] returns ['c', 'b', 'a'] Your output reverse_list() function reversed array incorrectly: ['c', 'b', 'a'] reverse_list() function should have returned: ['a', 'b', 'c'] Test input list ['a', 'b', 'c', 'd'], first element of returned list is ['d'] Your output First character of returned array should be a instead of d Test empty input array TypeError: object of type 'NoneType' has no len()
