Solution

Sure, here is a step-by-step guide on how to insert a new node into a sorted circular linked list:

  1. Create a new node. Let's call it temp.

  2. If the circular linked list is empty, make the new node a self-loop and return.

  3. Initialize a pointer current to the head of the linked list.

  4. If the new node needs to be inserted at the beginning:

    • While current is pointing to the last node of the list (i.e., current->next != head), move current along the list.
    • Make current->next = temp.
    • Make temp->next = head.
    • Update head = temp.
  5. If the new node needs to be inserted in the middle:

    • Find a node in the list after which the new node is to be inserted. To find this node, start from head and find the first node which is not smaller than the new node. Let's call this node current.
    • While current->next is smaller than temp and current->next is not pointing to the head, move current along the list.
    • Make temp->next = current->next and current->next = temp.
  6. If the new node needs to be inserted at the end:

    • While current is pointing to the last node of the list (i.e., current->next != head), move current along the list.
    • Make current->next = temp.
    • Make temp->next = head.

This way, the new node is inserted into the sorted circular linked list while maintaining the sorted order.
