SpletSwapping two nodes requires creating a temporary pointer temp which points to the next node which is to be swapped. Later on, swapping can be achieved by simply changing the links of the node’s next pointer and the corresponding nodes are swapped. To better comprehend the solution, let's take a look at the entire algorithm. Algorithm SpletIn the swap function, 1. If x and y are same, do nothing just return the same linked list. 2. Search for x and y, if either of x or y is not present, do nothing just return the same linked list. 3. If x is not head, make x_prev->next as y, else make y as new head. 4. If y is not head, make y_prev->next as x, else make x as new head. 5.
