Implement the function below void swap(int pos1, int pos2) {} For LinkedList, to maintain integrity of data in the structure, you are not to swap directly the element, nor remove a node. Instead, you are to only change the nodes' next pointers. Inital code to be completed: class LinkedList : public List { node* head; node* tail; int index; node* create_node(int num) { node* n = (node*) malloc(sizeof(node)); n->element = num; n->next = NULL; return n; } public: LinkedList() { index = 0; head = NULL; tail = NULL; } int add(int num) { addTail(num); return index; } int get(int pos) { node* currnode = head; int count =0; while (currnode != NULL){ count++; if (count == pos){ return currnode -> element; }else{ currnode = currnode -> next; } }…

Write a Python code using the given function and conditions. Do not use Numpy. Use LinkedList Manipulation. Given function: def insert(self, newElement, index) Pre-condition: The list is not empty. Post-condition: This method inserts newElement at the given index of the list. If an element with the same key as newElement value already exists in the list, then it concludes the key already exists and does not insert the key. [You must also check the validity of the index].
Given a list mylist construct a dictionary mydict, the key is the index of an element in my list and its value will be the element value of mylist. for example the index of "a" is "0" . therefore the pair ( 0,"a" )will be in mydict .it means mydict = { 0:'a' ,1:'cybersecurity ', 2 : 'newyork'......} Do this in coding but not manually. given an empty dictionary mydict ={} write a python code to construct mydict for any given list. Hint : Your Code begins with mydict={}for val in mylist:
# viewGame(G, i) takes a game description G (a dictionary of the type# produced by newGame()) and an integer player index i and returns a# string that, when printed, describes the state of the game from# player i's perspective.## Example:# >>> viewGame(G, 1)# '\nPlayer2 to play (score=0):\n 1[ ] 2[ ] 3[ ]'## Note the spacing and explicit newlines, and the fact that the player# numbers use 1-based indexing even though internally the game data# structures use Pythonic 0-based indexing.
