1 Answer

Answer :

Your description in the problem doesn’t really describe what you want it to do that you would call right, nor does it explain how it uses its linked list. If you haven’t figured out exactly what you want it to do in a consistent way that you can express, then no, you can’t do it right, because there’s nothing right to do. Once you do have a model of what you want to do that you can describe clearly, then yes, there will be a right way to do it.

How do you find out if a linked-list has an end? (i.e. the list is not a cycle)

Description : How do you find out if a linked-list has an end? (i.e. the list is not a cycle)

Last Answer : You can find out by using 2 pointers. One of them goes 2 nodes each time. The second one goes at 1 nodes each time. If there is a cycle, the one that goes 2 nodes each time will eventually meet the one that goes slower. If that is the case, then you will know the linked list is a cycle.
