WebAug 20, 2024 · Let us first think about what we need to perform the required task of rotating the list counter-clockwise by X nodes. For linked list rotation, we have to change the next of X th node to NULL, next of the last node to the head node, and finally, make the head point to the (X+1) th node. So, we need X th node, (X+1) th node and the last node.
