code that highlights the bug

class Solution:
    def hasCycle(self, head: Optional[ListNode]) -> bool:
        output = False
        s, f = head,  head.next.next if head.next else None
        while f:
            if s == f:
                output = True
                break
            s = s.next
            f = f.next.next if f.next else None
        return output
