To detect a cycle in a linked list, you can use floyd’s tortoise and hare algorithm, also known as the two pointer technique. here’s the dart code to determine if a linked list has a. Detecting cycles is a common interview question because it tests pointer logic, space time tradeoffs, and an efficient algorithmic trick. given head, the head of a linked list, determine if the linked list has a cycle in it.

Detecting cycles is a common interview question because it tests pointer logic, space time tradeoffs, and an efficient algorithmic trick. given head, the head of a linked list, determine if the linked list has a cycle in it. There is a cycle in a linked list if at least one node in the list can be visited again by following the `next` pointer. internally, `index` determines the index of the beginning of the cycle, if it exists. Trace a list 1 → 2 → 3 → 4 → 2 (node 4 points back to node 2). initialize: slow = 1, fast = 1. step 1: slow = 2, fast = 3. step 2: slow = 3, fast = 2 (fast went 4 → 2). step 3: slow = 4, fast = 4. they meet at node 4. return true. for a list without cycle: fast reaches null and we return false. slow moves n n steps at most. This is a classic singly linked list problem and a very popular one in coding interviews, especially at the mid and entry levels. it requires you to have a good understanding of linked lists and basic pointer manipulation.
