Solving Common Linked List Problems: Kth-from-End, Palindrome Check, and Intersection Detection

Finding the Kth Node from the End of a Linked List To locate the kth node from the end efficient, use two pointers—fast and slow. Advance the fast pointer by k steps first. Then move both pointers forward until fast reaches the end. At this point, slow will be pointing to the desired node. int kthToLast(struct ListNode* head, int k) { struc ...
