PYTHON CS1 PROBLEM Define a function that takes a dictionary gdict as a parameter and returns a list of values that are associated with only a single key in the dictionary. For example: 1. If gdict = ("a":3, "b": 4, "X": 3, "2": 5, "K": 4, "C": 1) then your function should return the list [1, 5]. 3 and 4 are not in the returned list because they are associated with more than one key. 2. If gdict = ("a":3,"b": 4, "X": 3, "K: 4) then your function should return the list [].

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.

- 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.

Create a new node with the given integer. Insert this node at the tail of the linked list and return the head node of the linked list formed after inserting this new node. The given head pointer may be null, meaning that the initial list is empty. Function Description Complete the insertNodeAtTail function in the editor below. insertNodeAtTail has the following parameters: SinglyLinkedListNode pointer head: a reference to the head of a list int data: the data value for the node to insert Returns SinglyLinkedListNode pointer: reference to the head of the modified linked list Input Format The first line contains an integer , the number of elements in the linked list.The next lines contain an integer each, the value that needs to be inserted at tail.

Provide the definitions of these functions in the class linkedListType. Also writea program to test these functions. (Use either the classunorderedLinkedList or the class orderedLinkedList to testyour function.) Note: Code in c++(IntelliJ) Write an easier version of a linked list with only a couple of the normal linked list functions and the ability to generate and utilize a list of ints. The data type of the connection to the following node can be just Node, and the data element can be just an int. You will need a reference (Java) or either a reference or a pointer (C++) to the first node, as well as one to the last node. * Create a method or function that accepts an integer, constructs a node with that integer as its data value, and then includes the node to the end of the list. If the new node is the first one, this function will also need to update the reference to the first node. This function will need to update the reference to the final node. Consider how to insert the new node following the previous last node, and keep in mind that the next reference for the list's last node should be null. * Create a different method or function that iteratively explores the list, printing the int data values as…
