To check whether a linked list has a loop
WebbIf there is a loop (of n nodes), then once a pointer has entered the loop it will remain there forever; so we can move forward in time until both pointers are in the loop. From here on the pointers can be represented by integers modulo n with initial values a and b. The condition for them to meet after t steps is then a + t ≡ b + 2 t mod n WebbIn the above example, we have implemented a LinkedList in Java. We have used Floyd's cycle finding algorithm to check if there is a loop in LinkedList. Notice the code inside …
