**Text Transcription for Educational Website**---In this section, we are focusing on sorting functionalities in programming, particularly for organizing lists of dictionaries based on specific criteria.### 5. sort_friends_by_name_lengthIn this function, we aim to sort a list of friend dictionaries by the length of their names in descending order. Breaking ties is not a concern for this task.**Instructions:**- Create a new output list to store the sorted dictionaries.- Avoid altering the original input list. Utilize slicing to duplicate the input list.- Use a function like `find_friend_with_longest_name` to identify which friend to add to the output list sequentially.> **Note:** Remember to remove each friend from the unsorted list once they have been added to the sorted output list.**Example:**```python>>> my_friends[{'name': 'bimmy', 'height': 60}, {'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}]>>> sort_friends_by_name_length(my_friends)[{'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}, {'name': 'bimmy', 'height': 60}]>>> my_friends[{'name': 'bimmy', 'height': 60}, {'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}]```### QuestionsIf you have any questions, feel free to seek help through the following:- Ask your TA.- Post your question on the course's online discussion platforms such as Canvas or Discord.- Engage with peers during discussion sections.---

5. sort friends_by_name_length In this function, we will again take a list of friend dictionaries (just like the previous problem), and we will return a new list where we have ordered the friends by the length of their names, decreasing. Don't worry about breaking ties. Make sure you create a new output list, and make sure not to destroy the input list! I recommend using slicing to copy the input list and then repeatedly calling find friend_with_longest_name to figure out who to put in the output list next. (note -- you'll have to find some way to remove each friend from the list of unsorted friends too) Sample runs should look like: >>> my_friends [{'name': 'bimmy', 'height': 60}, {'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}] >>> sort_friends_by_name_length(my_friends) [{'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}, {'name': 'bimmy', 'height': 60}] >>> my_friends [{'name': 'bimmy', 'height': 60}, {'name': 'Ian Donald Calvin Euclid Zappa', 'height': 175}]

***NEED HELP WITH THIS**** write a code that replicates the list's insert() method. Recall that insert(index, item) method inserts the item at specified index in the list. Write a code that: Asks the user to input 5 items in a list and display the list. Ask the user to input the index where they would like to insert a new item. Ask the user to input the item that they would like to insert into the list. Inserts the new item into the list and displays the modified list. If the index is greater than the length of the list, simply insert the new item at the end of list. Also i dont need to use the list's insert() method to do this program. I dont need to write a function, just the code to replicate the functionality of insert() method.

have been given a singly linked list of integers. Write a function that returns the index/position of integer data denoted by 'N' (if it exists). Return -1 otherwise. Note :Assume that the Indexing for the singly linked list always starts from 0.Input format :The first line contains an Integer 'T' which denotes the number of test cases. The first line of each test case or query contains the elements of the singly linked list separated by a single space. The second line contains the integer value 'N'. It denotes the data to be searched in the given singly linked list. Remember/Consider :While specifying the list elements for input, -1 indicates the end of the singly linked list and hence -1 would never be a list element. Output format :For each test case, return the index/position of 'N' in the singly linked list. Return -1, otherwise. Output for every test case will be printed in a separate line. Note:You do not need to print anything; it has already been taken care of. Just implement…
pls use phyton and write code clearly.. thank u for answer
I'm trying to create two functions where each calculates a cube. One that uses numpy and uses function power and can't use for loops. Other uses a range of intergers and returns a list of each range elements using pow. I can get each to cube but I can't figure out how to do it by defining a function. import numpy as nparray1 = np.array([3,5,10,9]) cubedarray1 = np.power(array1, 3)print('This is the cubed arrray 1: ', cubedarray1)array2 = range(1,10,2) # range is 1, 3, 5, 7, 9cubedarray2 = [pow(i, 3) for i in array2]print('This is the cubed array 2: ', cubedarray2)
Write a function sum67 that takes a list as an input parameter and returns the sum of the numbers in the list, except ignore sections of numbers starting with a 6 and extending to the next 7 (every 6 will be followed by at least one 7). Return 0 for no numbers.
In c++, please! Thank you! Write a void function SelectionSortDescendTrace() that takes an integer array and sorts the array into descending order. The function should use nested loops and output the array after each iteration of the outer loop, thus outputting the array N-1 times (where N is the size). Complete main() to read in a list of up to 10 positive integers (ending in -1) and then call the SelectionSortDescendTrace() function. If the input is: 20 10 30 40 -1 then the output is: 40 10 30 20 40 30 10 20 40 30 20 10 The following code is given: #include <iostream> using namespace std; // TODO: Write a void function SelectionSortDescendTrace() that takes// an integer array and the number of elements in the array as arguments,// and sorts the array into descending order.void SelectionSortDescendTrace(int numbers [], int numElements) { } int main() { int input, i = 0; int numElements = 0; int numbers [10]; // TODO: Read in a list of up to 10 positive…
Using Clojure Write a procedure, called count-to-1, that takes a positive integer n, and returns a list of the integers counting down from n to 1. For example, given input 3, it will return (list 3 2 1). Hint: Use the procedures reverse and count-to-n that you wrote in the previous problems. (Shown in attached image)
in this assignment i have to remove vowels from a string using a linked list. the linked list and link code is from a textbook and cannot be changed if the code alters the data structure. for some reason when i implement this code it gives me a logical error where the program only removes all instances of the first vowel in a string instead of moving through all vowels of the string and removing each one with all instances. i would appreciate if you could tell me the problem and solution in words and not in code.
