NettetMain Concepts. Before going more in depth on what linked lists are and how you can use them, you should first learn how they are structured. Each element of a linked list is called a node, and every node has two different fields:. Data contains the value to be stored in the node.; Next contains a reference to the next node on the list.; Here’s what a typical … NettetThis idea of detecting cycles in a linked list is based on an algorithm known as Floyd's cycle finding algorithm or the tortoise and the hare algorithm. This algorithm uses two …

The pointer always points to the next … Nettet9. sep. 2024 · Consider a linked list of some nodes which also contains a loop. First, identify the length of the loop. Use slow and fast pointer and move them until they point to the same node. Now keeping slow pointer constant, move the fast pointer by one until it reaches to slow pointer again, thereby giving the length of the loop.
