WebJan 11, 2024 · The algorithm is to start two pointers, slow and fast from head of linked list. We move slow one node at a time and fast two nodes at a time. If there is a loop, then they will definitely meet. This approach works because of the following facts. 1) When slow pointer enters the loop, the fast pointer must be inside the loop.

WebThe detect loop method is detecting the loop in the linked list. s.insert () is adding the node into the hash table if the node is traversed for the first time.if the node is already in the hash then s.find (head) != s.end () will return true.if there is no loop the method will return false. Time complexity: Big O (n) WebThis 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 pointers, a "slow" pointer and a "fast" pointer, that move through the list at different speeds. At each iteration step, the slow pointer moves one step while the fast ...
