algorithm: swap linked list.
Given a linked list that stored integer values as follows: Node 1 --> Node 2 --> Node 3 --> Node 4... Write an algorithm that to swap each element with its immediate neighbour. Should an odd number of nodes exist, the last node is not swapped. Additionally, only entire nodes should be swapped. Changing the values of the nodes is not allowed. The final result should be as follows: Node 2 --> Node 1 --> Node 4 --> Node 3 TE Write the algorithm to do the swapping in a single pass
