WebFeb 27, 2024 · Change the next of the kth node to NULL. Change the next of the last node to the previous head node. Change the head to (k+1)th node. In order to do that, the pointers to the kth node, (k+1)th node, and last node are required. Below is the implementation of the above approach: Web1. Set next of q as NULL (q-next = NULL). 2 . Set next of p as head (p->next = head). 3. Make head as p (head = p) Step 2 must be performed before step 3.

Web1. Set next of q as NULL (q-next = NULL). 2 . Set next of p as head (p->next = head). 3. Make head as p (head = p) Step 2 must be performed before step 3. If we change head first, then we lose track of the head node in the original linked list.
