WebThe problem mentions rotating the list to the right. We first have to get the total number of nodes in the list. If k is greater than the list length, we first take the modulo of k by list length and then subtract the value of k from the list length. If k is smaller, we subtract the value of k from the list length. WebTo solve the problem, first, we need to find the length of the linked list and the tail node. Then we calculate the effective rotation length. If k is equal to the length of the list or a multiple of the length of the list, the list remains unchanged. Otherwise, we find the new tail node and the new head node by traversing the linked list.
