Question

Write the Python code for finding the second-to-last (item
before the last) node in a Singly Linked list in which the
last node is indicated by a next reference of None. If there
is no second-to-last node, return None. The Linked list
contains a reference to the first node in the list only
(head). This operation should not modify the original list .
Do not use the Tab key to denote indentation, instead,
use the space bar
Example:
For the list 3 -> 5 -> 8 -> 9, second_to_last returns the
reference to the Node with value 8
def second_to_last(self):

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.

Write a Python program that creates a linked list with 10000 nodes. Each node has arandom number between -1000 and 1000. Write a Python program that sort the linked list of above question in ascending order using theinsertion sort.
Write a program REMOVE_DUPLICATES that will remove duplicateelements in a list L that occur consecutively. The program should return the list withits elements in the same order of their appearance in the original list, but with theconsecutive duplicate elements removed.For example, for a list with elements {A, B, C, C, C, C, D, D, E, F, F}, theoutput list produced by REMOVE_DUPLICATES should be {A, B, C, D, E, F}.
Write a program in python with a function isPal(L), where L is a list of integers, and the function returns True if the list is a palindrome, False otherwise. For example [5, 2, 9, 9, 2 5] is a palindrome. Use the reverse() method of list and check if the reversed list is the same as the original list.
Write a java program to insert one element in a singly linked list before a given element. Your program will print the original list, request the user to put in an element to be inserted, and an element to indicate the location of the insertion, then print the final list after the insertion is done. If the element doesn't exist in the list, add the new element to the end of the list. No duplicate values are allowed to store in list. Once you done insertion operation (at least 10 element inserted) in your list, Draw a binary search tree and AVL tree ( show all rotations ) as per your inserted values . Use the following as your test cases to evaluate whether your program works correctly: If you have a linked list: 6à2à7. With user input 8 and 2. Your list should become 6à8à2à7: With user input 8 and -1. Your list should become 6à2à7à8: Let suppose your final linked list . 6à2à7à8à5à10à1à9à3
Write a program in c++ and make sure it works, that reads a list of students (first names only) from a file. It is possible for the names to be in unsorted order in the file but they have to be placed in sorted order within the linked list.The program should use a doubly linked list.Each node in the doubly linked list should have the student’s name, a pointer to the next student, and a pointer to the previous student. Here is a sample visual. The head points to the beginning of the list. The tail points to the end of the list. When inserting consider all the following conditions:if(!head){ //no other nodes}else if (strcmp(data, head->name)<0){ //smaller than head}else if (strcmp(data, tail->name)>0){ //larger than tail}else{ //somewhere in the middle} When deleting a student consider all the following conditions:student may be at the head, the tail or in the middleBelow, you will find a sample of what the file looks like. Notice the names are in…
Python Implement a singly linked list with the following functions: - add_head(e) - add_tail(e) - find_3rd_to_last() - returns element located at third-to-last in the list - reverse() - reveres the linked list, note, this is not just printing elements in reverse order, this is actually reversing the list
Given the head of a singly linked list of integers, write the function to arrange the elements such thatall the even numbers are placed after all the odd numbers. The relative order of the odd and eventerms should remain unchanged.Input Format:Elements of linked listOutput Format:Resultant linked listSample Input 1:1 4 5 2Sample Output 1:1 5 4 2Sample Input 2:1 11 3 6 8 0 9Sample Output 2:1 11 3 9 6 8 0 in java

Write a Python function `removeDuplicates(myList)` that removes duplicate values from a list. While the algorithm for this problem might seem trivial, its implementation is not. In general, it is not advisable to modify a list while you are iterating on it, as in the following pseudo-code: for element in myList: if <condition>: <remove element(s) from myList> # recipe for disaster
Implement a priority queue (for both max and min, one time the bigger numbers should have higher priority, other time the smaller numbers should have higher priority ) in python using a linked list. The priority queue should have four functions, 1/ insert(item, priorityValue), peek(), delete(), changePriority(item, newPriority).
