I have create a function int reverseNum(Node *head) to get number from reverse linked list.
eg. for Linked List:- 1->2->3->4 the number will be 4321.
But the program is returning 4320.

int List::size() { // FIXME: implement this method to return the number of Nodes in the list int listSize = 0; Node* temp = first; while (temp != nullptr) { listSize++; temp = temp->next; } return listSize; } I’m implementing this linked list class method to calculate the number of nodes in the list. When […]

I was trying to insert a node at the end of the linked list. It could be compiled and run in the right way but it didn’t print out anything. Is it wrong with the `Insert(int data)’or ‘Print()’?
Here is my code.

I need to use the Quicksort sorting algorithm to sort elements of a linked list. It is important to note that I must not just swap the key values, but the elements themselves. My code simply does not work; I believe I am making a mistake with the recursion. I would like a solution.

So, if I have a singly linked list that looks like: 2 6 7 8 9
