You have given a Singly Linked List of integers, determine if it forms a cycle or not. A cycle occurs when a node's next points back to a previous node in the list. The linked list is no longer linear with a beginning and end—instead, it cycles through a loop of nodes. Note: Since, it is binary problem, there is no partial marking. おみくじ勇WebExplanation of the Method detect loop. The 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. parisi coan \u0026 saccocio pllc
