Finding loop in a singly linked-list - Stack Overflow

WebFeb 27, 2011 · If the list does not contain a cycle, then all these values are distinct. If it does contain a cycle, though, then this sequence will repeat endlessly. Here's the theorem that makes Floyd's algorithm work: The linked list contains a cycle if and only if there is a positive integer j such that for any positive integer k, x j = x jk. WebFeb 7, 2024 · Python3. The original list is : [ ('Gfg', [1, 3, 4]), ('is', [5, 8, 10]), ('best', [11, 9, 2])] The required key of list values : Gfg. This approach uses a for loop to iterate through the elements in the list and check if the value of K is present in the second element of each tuple.

WebJan 2, 2024 · Python Program for Detect Cycle in a Directed Graph. Given a directed graph, check whether the graph contains a cycle or not. Your function should return true if the given graph contains at least one cycle, else return false. For example, the following graph contains three cycles 0->2->0, 0->1->2->0 and 3->3, so your function must return … WebA loop or a cycle in graph theory is a path of nodes and edges where a node is reachable from itself..
