<prompt> Kwa kuwa kichwa, kichwa cha orodha iliyounganishwa, kuamua kama orodha iliyounganishwa ina mzunguko ndani yake. Kuna mzunguko katika orodha iliyounganishwa ikiwa kuna node fulani katika orodha ambayo inaweza kufikiwa tena kwa kufuata pointer inayofuata. Ndani, pos hutumiwa kuashiria faharisi ya node ambayo pointer inayofuata ya mkia imeunganishwa. Kumbuka kuwa pos haipitwi kama parameter. Rudi kweli ikiwa kuna mzunguko katika orodha iliyounganishwa. Vinginevyo, rudi uwongo.  <response>: One approach to detect the cycle in a linked list is Floyds cycle-finding algorithm, also known as hare and tortoise algorithm. In this approach, two pointers, a slow pointer and a fast pointer, traverse the linked list. If the linked list contains a cycle, eventually, the fast pointer will catch up with the slow pointer.Heres the code for implementing Floyds algorithm:bool hasCycleListNode head if head nullptr head-next nullptr return false; ListNode slow head; ListNode fast head-next; while slow ! fast if fast nullptr fast-next nullptr return false; slow slow-next; fast fast-next-next; return true;The time complexity of this algorithm is On and the space complexity is O1, where n is the number of nodes in the linked list.
