WebJul 17, 2024 · The problem is to detect loops in a singly linked list. This is an obvious use of Floyd's cycle finding algorithm, but I can't seem to get it to work. I also checked my answer to others, and it seems to be doing the same thing. If anyone can help me out I would appreciate it. // Complete the hasCycle function below. WebJan 30, 2024 · In detecting the cycle, depending on where the cycle occurs, the fast and slow pointers may not meet on the first iteration through the linked list. But it will catch it after a certain constant number of cycles, let's call it k cycles. Therefore the runtime is k * O (n) which results in the linear runtime complexity.
